The Rule of 4 and 2: For a lot of players including myself , the best way to learn about something is through a bunch of examples.

So, carrying on from the basics outlined in my first article on pot odds , here are a bunch of examples for you to get your teeth in to.

I will be incorporating a little of the concepts of implied odds and reverse implied odds for good measure.

Try your best to work out whether you should call or fold and why before revealing the answer. Furthermore, the stakes used in each example are not a refelection of the ability of the players at the table, so don't read too much in to that.

Strategy "in a vacuum" if you will. Pot odds are not good enough. We ideally need pot odds of 4: This is an asymptotic approximation, and will not give a meaningful result if any of the cell counts are very small.

An alternative approach to inference for odds ratios looks at the distribution of the data conditionally on the marginal frequencies of X and Y.

An advantage of this approach is that the sampling distribution of the odds ratio can be expressed exactly.

Logistic regression is one way to generalize the odds ratio beyond two binary variables. Suppose we have a binary response variable Y and a binary predictor variable X , and in addition we have other predictor variables Z 1 , If we use multiple logistic regression to regress Y on X , Z 1 , Specifically, at the population level.

In many settings it is impractical to obtain a population sample, so a selected sample is used. In this situation, our data would follow the following joint probabilities:.

This shows that the odds ratio and consequently the log odds ratio is invariant to non-random sampling based on one of the variables being studied.

Note however that the standard error of the log odds ratio does depend on the value of f. In both these settings, the odds ratio can be calculated from the selected sample, without biasing the results relative to what would have been obtained for a population sample.

Due to the widespread use of logistic regression , the odds ratio is widely used in many fields of medical and social science research.

The odds ratio is commonly used in survey research , in epidemiology , and to express the results of some clinical trials , such as in case-control studies.

It is often abbreviated "OR" in reports. When data from multiple surveys is combined, it will often be expressed as "pooled OR".

In clinical studies, as well as in some other settings, the parameter of greatest interest is often the relative risk rather than the odds ratio.

If the absolute risk in the control group is available, conversion between the two is calculated by: Odds ratios have often been confused with relative risk in medical literature.

For non-statisticians, the odds ratio is a difficult concept to comprehend, and it gives a more impressive figure for the effect. This may reflect the simple process of uncomprehending authors choosing the most impressive-looking and publishable figure.

This is known as the 'invariance of the odds ratio'. In contrast, the relative risk does not possess this mathematical invertible property when studying disease survival vs.

This phenomenon of OR invertibility vs. RR non-invertibility is best illustrated with an example:. As one can see, a RR of 0. In contrast, an OR of 0.

This is again what is called the 'invariance of the odds ratio', and why a RR for survival is not the same as a RR for risk, while the OR has this symmetrical property when analyzing either survival or adverse risk.

The danger to clinical interpretation for the OR comes when the adverse event rate is not rare, thereby exaggerating differences when the OR rare-disease assumption is not met.

On the other hand, when the disease is rare, using a RR for survival e. When one or more of the cells in the contingency table can have a small value, the sample odds ratio can be biased and exhibit high variance.

A number of alternative estimators of the odds ratio have been proposed to address this issue. One alternative estimator is the conditional maximum likelihood estimator, which conditions on the row and column margins when forming the likelihood to maximize as in Fisher's exact test.

The following four contingency tables contain observed cell counts, along with the corresponding sample odds ratio OR and sample log odds ratio LOR:.

The following joint probability distributions contain the population cell probabilities, along with the corresponding population odds ratio OR and population log odds ratio LOR:.

However, certain widely-circulated gambling strategies that at first appear to be "common sense" are, in fact, mathematically false.

Below are just a few things you should keep in mind when you go gambling - don't lose more money than you have to! You're never "due" to win.

If you've been at the Texas Hold 'Em table for an hour and you haven't been dealt a single good hand, you may want to stay in the game in the hopes that a winning straight or flush is "right around the corner.

The cards are randomly shuffled before every deal, so if you've had ten bad hands in a row, you're just as likely to get another bad hand as you are if you've had a hundred bad hands in a row.

This extends to most other games of chance - roulette, slots, etc. Sticking with one specific bet won't increase your odds.

You may know someone who has "lucky" lotto numbers - though it can be fun to bet money on numbers that have special personal meaning, in random games of chance, you're never more likely to win by betting on the same thing every time than you are by betting on a different thing every time.

Lottery numbers, slots, and roulette wheels are completely random. In roulette, for example, it's just as likely that you'll roll "9" three times in a row as it is that you'll roll any specific three numbers in order.

If you're one away from the winning number, you weren't "close. You weren't even close. Two numbers that are close together, like 41 and 42, aren't mathematically connected in any way in random games of chance.

What is my chance to win once in three draws of a one-in-five chance to win? The chance of losing all three is. Thus, the chance of not losing all three is 1 -.

So the probability of winning at least once is Not Helpful 8 Helpful There are two possible outcomes and one "right" outcome.

One out of two is 50 out of , or Not Helpful 0 Helpful 3. Give the odds in simplest form. Not Helpful 6 Helpful 8. Now, it depends on what you mean by "better".

Not Helpful 3 Helpful 3. Assuming the event which is being predicted has only 2 outcomes, and is random, and each prediction is one of these 2 outcomes, the chance of all ten predictions being accurate would be 0.

If I have a 1 in 5, chance of winning on a given day, and I play every day, how many times am I likely to win in a year?

You are not likely to win in a year. If you divide by days in a year you get Not Helpful 5 Helpful 2. Not Helpful 62 Helpful 7. A total of raffle tickets were sold.

One person purchased 5 tickets. What are the odds of one of his tickets being drawn? It depends on how many tickets are drawn.

If only one ticket is drawn, the odds are 5 out of , or roughly 1 in Not Helpful 0 Helpful 0. Is there a formula to use in soccer betting to win?

Answer this question Flag as I have a game that has 46 balls. What is the probability all 6 red balls will pop up at once? And what are the odds of winning if people play each drawing?

With a random draw, you have 12 entries out of 80 total entries. What is the probability that none of your entries will be in the first 25 picks?

If I have 2 sets of cards comprised of 12 Aces and 13 kings respectively, what are the odds of getting only kings if 6 cards are dealt? Include your email address to get a message when this question is answered.

Already answered Not a question Bad question Other. Tips Check the rules for the specific game you are playing for further information that will help you calculate odds.

Calculating the odds of a lottery is a lot harder. Charts where the odds are already calculated for you are available on the Internet.

Look for free real time odds web services that will guide you in how the odds makers are calculating the odds for upcoming sporting events.

Warnings Know that in any gambling, the odds are against your winning. This increases when you play a random game that doesn't depend on previous outcomes, such as slot machines.

Article Summary X To calculate odds, start by determining the number of favorable outcomes and the number of unfavorable outcomes.

Eine Dame würde dir wiederum ein Full-House geben. Die Outs bezeichnen dabei die Anzahl der Karten, die die eigene Hand verbessern. Du denkst, dass dein gegner KK hat. Sie halten A-K am Button. Und genau deshalb sind unsere mathematischen Gleichungen auch ganz simpel. Das ist die simple Tipico gutscheine hinter den Implied Odds. Sie werden sich auf Dauer nicht darauf beschränken können, nur zu callen, wenn Sie momentan die korrekten Odds dazu bekommen. Flush-Draw mitgehen sollst oder nicht. Die Outs bezeichnen dabei die Anzahl der Karten, die die eigene Hand verbessern. Navigation Hauptseite Themenportale Zufälliger Artikel. Umstände der Hand, wie sie momentan ist. Du hast also ein Straight Draw am Turn. Damit gilt für die Wahrscheinlichkeit, seine Karten durch die River-Karte zu verbessern, fast das gleiche:. Poker Guide Beste Pokerseiten. Manchmal ist es einfach, deine Outs zu zählen, besonders wenn du einen Draw auf die Nuts hast. Ein Gegner setzt einen Einsatz in Höhe des Pots. Sehen wir uns den Gutshot genauer an.Differentiate between dependent and independent events. In certain scenarios, odds for a given event will change based on the results of past events.

For example, if you have a jar full of twenty marbles, four of which are red and sixteen of which are green, you'll have 4: Let's say you draw a green marble.

If you don't put the marble back into the jar, on your next attempt, you'll have 4: Then, if you draw a red marble, you'll have 3: Drawing a red marble is a dependent event - the odds depend on which marbles have been drawn before.

Independent events are events whose odds aren't effected by previous events. Flipping a coin and getting a heads is an independent event - you're not more likely to get a heads based on whether you got a heads or a tails last time.

Determine whether all outcomes are equally likely. If we roll one die, it's equally likely that we'll get any of the numbers 1 - 6.

However, if we roll two dice and add their numbers together, though there's a chance we'll get anything from 2 to 12, not every outcome is equally likely.

There's only one way to make 2 - by rolling two 1's - and there's only one way to make 12 - by rolling two 6's. By contrast, there are many ways to make a seven.

For instance, you could roll a 1 and a 6, a 2 and a 5, a 3 and a 4, and so on. In this case, the odds for each sum should reflect the fact that some outcomes are more likely than others.

Let's do an example problem. To calculate the odds of rolling two dice with a sum of four for instance, a 1 and a 3 , begin by calculating the total number of outcomes.

Each individual dice has six outcomes. Take the number of outcomes for each die to the power of the number of dice: Next, find the number of ways you can make four with two dice: So the odds of rolling a combined "four" with two dice are 3: Your odds of rolling a "yahtzee" five dice that are all the same number in one roll are very slim - 6: Take mutual exclusivity into account.

Sometimes, certain outcomes can overlap - the odds you calculate should reflect this. For instance, if you're playing poker and you have a nine, ten, jack, and queen of diamonds in your hand, you want your next card either to be a king or eight of any suit to make a straight , or, alternatively, any diamond to make a flush.

Let's say the dealer is dealing your next card from a standard fifty-two card deck. There are thirteen diamonds in the deck, four kings, and four eights.

The thirteen diamonds already includes the king and eight of diamonds - we don't want to count them twice. Thus, the odds of being dealt a card that will give you a straight or flush are In real life, of course, if you already have cards in your hand, you're rarely being dealt cards from a complete fifty-two card deck.

Keep in mind that the number of cards in the deck decreases as cards are dealt. Also, if you're playing with other people, you'll have to guess what cards they have when you're estimating your odds.

This is part of the fun of poker. Know common formats for expressing gambling odds. If you're venturing into the world of gambling, it's important to know that betting odds don't usually reflect the true mathematical "odds" of a certain event happening.

Instead, gambling odds, especially in games like horse racing and sports betting, reflect the payout that a bookmaker will give on a successful bet.

To add to the confusion, the format for expressing these odds sometimes varies regionally. Here are a few non-standard ways that gambling odds are expressed: Decimal or "European format" odds.

These are fairly easy to understand. Decimal odds are simply expressed as a decimal number, like 2. This number is the ratio of the payout to the original stake.

For instance, with odds of 2. Fractional or "UK format" odds. This represents the ratio of the profit not total payout from a successful bet to the stake.

Moneyline or "US format" odds. These can be difficult to understand. Remember this subtle distinction! In moneyline odds, a simple "" no plus or minus represents an even bet - whatever money you stake, you'll earn as profit if you win.

Understand how gambling odds are set. The odds that bookmakers and casinos set aren't usually calculated from the mathematical probability that certain events will occur.

Rather, they're carefully set so that, in the long run, the bookie or casino will make money, regardless of any short-term outcomes! Take this into account when making your bets - remember, eventually, the house always wins.

Let's look at an example. A standard roulette wheel has 38 numbers - 1 through 36, plus 0 and If you bet on one space let's say 11 , you have 1: However, the casino sets the payout odds at Notice that the payout odds are slightly lower than the odds against you winning.

If casinos weren't interested in making money, you would be paid out at However, by setting the payout odds slightly below the actual odds of you winning, the casino will gradually make money over time, even if it has to make the occasional large payout when the ball lands on Don't fall prey to common gambling fallacies.

Gambling can be fun - even addictive. However, certain widely-circulated gambling strategies that at first appear to be "common sense" are, in fact, mathematically false.

Below are just a few things you should keep in mind when you go gambling - don't lose more money than you have to! You're never "due" to win.

So the probability of winning at least once is Not Helpful 8 Helpful There are two possible outcomes and one "right" outcome.

One out of two is 50 out of , or Not Helpful 0 Helpful 3. However, it is standard in the literature to explicitly report the OR and then claim that the RR is approximately equal to it.

The odds ratio is the ratio of the odds of an event occurring in one group to the odds of it occurring in another group. The term is also used to refer to sample-based estimates of this ratio.

These groups might be men and women, an experimental group and a control group , or any other dichotomous classification. If the probabilities of the event in each of the groups are p 1 first group and p 2 second group , then the odds ratio is:.

An odds ratio of 1 indicates that the condition or event under study is equally likely to occur in both groups. An odds ratio greater than 1 indicates that the condition or event is more likely to occur in the first group.

And an odds ratio less than 1 indicates that the condition or event is less likely to occur in the first group. The odds ratio must be nonnegative if it is defined.

It is undefined if p 2 q 1 equals zero, i. The odds ratio can also be defined in terms of the joint probability distribution of two binary random variables.

The joint distribution of binary random variables X and Y can be written. However note that in some applications the labeling of categories as zero and one is arbitrary, so there is nothing special about concordant versus discordant values in these applications.

Other measures of effect size for binary data such as the relative risk do not have this symmetry property.

In this case, the odds ratio equals one, and conversely the odds ratio can only equal one if the joint probabilities can be factored in this way.

Thus the odds ratio equals one if and only if X and Y are independent. If the odds ratio R differs from 1, then. Once we have p 11 , the other three cell probabilities can easily be recovered from the marginal probabilities.

Suppose that in a sample of men, 90 drank wine in the previous week, while in a sample of women only 20 drank wine in the same period. The odds of a man drinking wine are 90 to 10, or 9: The detailed calculation is:.

This example also shows how odds ratios are sometimes sensitive in stating relative positions: The logarithm of the odds ratio, the difference of the logits of the probabilities , tempers this effect, and also makes the measure symmetric with respect to the ordering of groups.

One approach to inference uses large sample approximations to the sampling distribution of the log odds ratio the natural logarithm of the odds ratio.

If we use the joint probability notation defined above, the population log odds ratio is. If we observe data in the form of a contingency table.

The sample log odds ratio is. The distribution of the log odds ratio is approximately normal with:. The standard error for the log odds ratio is approximately.

This is an asymptotic approximation, and will not give a meaningful result if any of the cell counts are very small.

An alternative approach to inference for odds ratios looks at the distribution of the data conditionally on the marginal frequencies of X and Y.

An advantage of this approach is that the sampling distribution of the odds ratio can be expressed exactly. Logistic regression is one way to generalize the odds ratio beyond two binary variables.

Suppose we have a binary response variable Y and a binary predictor variable X , and in addition we have other predictor variables Z 1 , If we use multiple logistic regression to regress Y on X , Z 1 , Specifically, at the population level.

In many settings it is impractical to obtain a population sample, so a selected sample is used. In this situation, our data would follow the following joint probabilities:.

This shows that the odds ratio and consequently the log odds ratio is invariant to non-random sampling based on one of the variables being studied.

Note however that the standard error of the log odds ratio does depend on the value of f. In both these settings, the odds ratio can be calculated from the selected sample, without biasing the results relative to what would have been obtained for a population sample.

Due to the widespread use of logistic regression , the odds ratio is widely used in many fields of medical and social science research.

The odds ratio is commonly used in survey research , in epidemiology , and to express the results of some clinical trials , such as in case-control studies.

It is often abbreviated "OR" in reports. When data from multiple surveys is combined, it will often be expressed as "pooled OR".

In clinical studies, as well as in some other settings, the parameter of greatest interest is often the relative risk rather than the odds ratio.

If the absolute risk in the control group is available, conversion between the two is calculated by: Odds ratios have often been confused with relative risk in medical literature.

For non-statisticians, the odds ratio is a difficult concept to comprehend, and it gives a more impressive figure for the effect.

This may reflect the simple process of uncomprehending authors choosing the most impressive-looking and publishable figure. This is known as the 'invariance of the odds ratio'.

In contrast, the relative risk does not possess this mathematical invertible property when studying disease survival vs. This phenomenon of OR invertibility vs.
