# Introduction

An understanding of basic probabilities will give your poker game a stronger foundation, for all game types. This article discusses all the important, and interesting, probabilities that you should be aware of.

# Probabilities in poker

Probability means the degree of certainty that a possible event will occur. The classic definition is: "The probability of an event is the ratio of the number of cases favorable to it, to the number of all cases possible when nothing leads us to expect that any one of these cases should occur more than any other, which renders them, for us, equally possible." The probability of flipping heads in a coin toss is therefore 1 to 2, or 50%.

For poker players, stochastics is the most interesting part of studying probability. Stochatics deals with frequence-based probabilities. Combinatorics (card combinations), statistics (sample size) and other subdisciplines are all a part of stochastics.

Probabilities are always a number between 0 and 1 and are usually expressed as a percentage. Probability can also be given as odds, which tells how often one event will occur in relation to the number of times another event will take place (1:2).

In the following sections you will get an overview of many useful probabilities that will help you improve your game. You can see the calculations used to arrive at these results on the second page of this article.

# Probability of being dealt a given starting hand

The following chart tells you exactly how likely you are to be dealt a given starting hand. Knowing these values can be very helpful when estimating the strength of your starting hand.

# Probability of making a specific hand (5 out of 52)

The following chart shows the probability of making a specific hand. You'll have the pleasure of holding a pair often enough; a straight or even royal flush is a lot less likely. 5 out of 52 means that you build your hand with using 5 cards.

# Probability of making a specific hand (7 out of 52)

The following chart shows the probability of getting a certain hand. Whereas a pair floats by often enough, getting a straight or royal flush is less likely.

7 out of 52 means, that although you build your hand using 5 cards, you still have 7 cards from which to choose these 5. In the case of Texas Hold'em, there's the 2 pocket cards and 5 on the board. This way of working out the probabilities would be the more accurate way - however, just to note, the probabilities worked out on 5 of 52 are practically the same, and far easier to calculate.

Probability:
In odds: 81.9:1

Example 2:

Range: AA, KK, QQ
Number of combinations: 18 (6 per hand)

Probability:
In odds: 72.7:1

# 2. Probability of facing a higher pocket pair when you have a pocket pair

a) Probability that a single opponent's pair will be higher

r = Rank of your pocket pair (2=2,... ,J=11, Q=12, K=13, A=14)

There are (14 – r) x 4 higher cards. Your opponent can have any of the 50 remaining cards (you have the other 2). If his first card is higher than your pocket pair, 3 of the 49 remaining cards could give him a higher pair.

b) Probability that one of several opponents' pairs will be higher
Start by multiplying the probability of one player having a higher pair with the number of players remaining in the hand (n). Then subtract the probability that more than one opponent has a higher pocket pair. ().

n = Number of players remaining in the hand
Probability that several opponents have a pocket pair, for which

Probability that exactly n players have a pocket pair, for which .

# 3. Probability of facing several higher pocket pairs

This is derived by the same principle, however: , for which

# 4. Probability of facing a better A

a) The probability than a specific opponent will have AA when you have an Ax hand

There are 50 cards remaining (you hold two, one of which is an ace), three of which are aces. If your opponent's first card is an ace, there are 2 of 49 remaining cards that could give him AA.

b) Probability that an opponent has AA when you have an Ax hand

n = Number of opponents

c) Probability that a single opponent will have a better A when you have an Ax hand

for which r represents the rank of your second (kicker) card (2=2,..., J=11, Q=12, K=13)

# 5. Probability that no overcard will come when you have a pocket pair

a) Preliminary considerations

Possible flops by any starting hand:

Possible turns by any starting hand:

Possible rivers by any starting hand:

b) No overcard on the flop

, for which r represents the rank of your pocket pair (2=2,..., J=11, Q=12, K=13)

c) No overcard on turn

for which r represents the rank of your pocket pair (2=2,..., J=11, Q=12, K=13)

d) No overcard on river

for which r represents the rank of your pocket pair (2=2,..., J=11, Q=12, K=13)

# 6. Probability of being dealt a specific hand

The probability of being dealt a specific hand is derived by dividing the number of possible card combinations for said hand by the number of all possible card combinations

# 7. Probability of improving on the flop

x represents the number of outs your hand has before the flop; y represents how many of these outs you want to hit; a represents the number of remaining cards (50 - # of outs); and b represents how many of these cards (a) you want to hit.

If you don't want to hit any of these cards, the term is not necessary. stands for the number of possible flop combinations (19600).

Example 3:

A pocket pair should improve to (exactly) three-of-a-kind on the flop

Example 4:

2 suited cards should improve to a completed flush on the flop

# 8. Probability of improving on the turn

Simple odds and outs. On the turn:

Note: If you want to calculate the probability that the even will not take place, you must subtract the result from 1.

# 9. Probability of improving on the river

Again, simple odds and outs. On the river:

# 10. Probability of improving from flop to river

Once again, it's a matter of calculating odds and outs:

The following formula can be used to calculating runner runner outs:

, for which Outs stands for runner runner outs. With a backdoor flush draw, for example, you have 10 outs for the flush draw and then 9 outs to complete.

Note: This cannot be used for straight/straight flush draws, since the outs depend on each other. In such a case the following formula can be used:

, for which x represents the number of outs for the first runner and y the number of outs for the second.

# 11. Probability of seeing a specific flop

This calculation does not take your or your opponent's cards into consideration, but calculates the probability of seeing a specific flop with 52 cards in the deck.

Option 1: This can be calculated with the help of binomial coefficients. For the number of possible card combinations for 3 of 52 cards we get . You then calculate the number of card combinations for a specific flop and divide by the number of all possible flops.

Here are a few examples to help illustrate this:

a) Probability of seeing three-of-a-kind in the flop
b) Probability of seeing three legs of a straight in the flop (without the possibility of a straight flush)

You subtract the 48 possible combinations that would also be part of a straight flush, since you only want to know the probability of seeing three legs of a normal straight on the flop.

Option 2:
You could also work with probabilities, you just have to make sure you are using the right ones. The first card can basically be any given card and will be written as , though it could be left out altogether. Then look at the events that should/should not take place and multiply the terms.

Here are a few examples to help illustrate this option better:

c) The probability of seeing three cards of the same suit on the flop

The simply shows that we start with any given card and can be left out of the formula, as it does not change the result in any way. and are the probabilities of the second and third card being the same suit as the first.
d) The probability of seeing a paired flop

Once again, the first card can be any given card. Once it has fallen, there are 3 of 51 remaining cards that could pair the board. Then one of the 48 cards that does not pair the board must come. You then multiply by 3 since the non-pair card could be any one of the three cards.

e) Probability that no suited cards will be in the flop

Here you multiply the probabilities of no two cards of the same suit appearing in the flop.

# Note

Converting probabilities to odds:

You have not yet learned to convert probabilities to odds. To do so, use this formula:

P represents the probability you wish to convert to odds. The ":" represents "to" as in '1 to 1' and does not mean to divide by 1.

You can also write instead of .

Nice one!

#6 RahXephon1, 04 Sep 09 10:29

Very nice article. Specially the part with the probability that a better hand wakes up after you. should be usefull to corectly judge the edge an isolation raise should have to be profitable.

The last part is interesting from a theorethic point of view, but it's probably easier to just remember the probabilities for the most important situations, than calculate them. Also the more marginal ones shouldn't be that important for calculating the profitability of the hand.

And BTW, can someone please explain to my opponents they have less than 1% to flop a flush, so they won't take my money everytime I go all in on a suited flop.

Just kidding obviously :)

what a great article.

thanks!

Great article, very useful!

It would also be nice to have the probabilities of improvement from three-of-a-kind to full house (or better) in the charts.

Thanks!

GUYS.... I LOVE U :)

Could someone please explain the calculation under 7. Probability of improving on the flop Example 3 where it calculated probability for hitting a set. Shouldn't it be 2C1*48C1*44C1/50C3. Actually what I calculated is also incorrect since that would lead to 4.6:1 odds and not 7.5:1 odds so can someone please explain the calculation here.

#22 maheepsangari, 23 Apr 12 12:53

I mean to calculate set or full house it would definitely be 2C1*48C2/50C3=11.51% meaning 7.68:1 odds so I'm wondering how to calculate for a set only directly without using the subtraction method.

#23 maheepsangari, 23 Apr 12 13:05

2C1*39C1/50C3 doesn't correspond to 11.5% but istead its 0.397%

Thank you that was very interesting and valuable information I have printed it out and I will try to memorise it thanks.

#25 coolpokername, 12 Dec 13 01:09

I know I'm not expected to memorize all this, but what am I supposed to do with this info?

good

Hi masheepsangari (@21)

You're right, I believe it's a mistake and they used wrong formula. When calculated it does give 0.397...% that you mention.
I calculated it myself and the probability of 11.5% is correct.

We have:
C1, C2 - cards of rank C that make the pocket pair
C3, C4 - cards of the rank C left in the deck of remaining 50 cards
E - the event of hitting a set only on the flop (while holding a pocket pair)

To hit a set only on the flop it means that we have hit either C3 or C4 and the remaining 2 cards are random.

To calculate number of events corresponding to E we will start from the back end:
Let's pick those 2 cards. From 48 cards we pick 2:
48! / [2!(48-2)!]
Now, those 2 cards come with the 3rd card - C3 or C4 so that makes twice that number:
because 2! = 2
we have:
48! / (48-2)! = 48! / 46! = 48*47 = 2256
and that's the number of events corresponding to E.

Total number of events (all possible flops): 19600

Now it's easy:
2256/19600 = 0.115... = 11.5%

Hope this helps!

nice

#32 FlyingDutchm1n, 08 Oct 15 23:49

Great overview right here I knew most of them but I especially found the stats on the straightyness (connectedness of the ranks like 3 connected straight ranks) superhelpful thank you pokerstrategy

#33 Leonventer112, 17 Oct 15 03:32

I love stats
