Poker Probability

Card Probability

Do you think that if the cards aren’t good, your odds of winning at the poker table are less? Maybe or maybe not! You must’ve heard that poker is a game of skill and with the right calculations, you can master the art of poker. But how? Read this blog to learn about the concept of poker probability.

One of the key aspects of playing poker is understanding the probabilities of different outcomes. In this blog, we'll go over some of the basic concepts of poker probability and provide examples of how they apply to the game. However, before that, let’s understand the concept of ‌‘probability’.

What is Probability?

In layman’s terms, probability means “possibility of happening”. Generally used in mathematics, probability explains how likely or to an extent something will happen. 

As we talk about the probability of something happening, understanding the possible outcomes becomes crucial. For instance, if you toss a coin, there are two possible outcomes, either you’ll get a head or a tail. Here the probability of getting a head or a tail is 50-50 each (one outcome out of the two). However, if you throw a die, there are six possible outcomes, i.e. you can get 1,2,3,4,5 or 6. In this case, the probability of getting one of them is 1/6.

Poker Probability

In poker, probability is the likelihood of a certain event happening. The most common events in poker are:

• Dealing a certain hand
• Winning a hand
• Making a specific hand (e.g. a flush or straight)

To calculate probabilities in poker, you need to know two things:

• The number of cards in the deck
• The number of cards that will help you achieve your desired outcome

For example, if you want to calculate the probability of being dealt a pocket pair (two cards of the same rank), you would do the following:

• There are 52 cards in the deck.
• There are 13 different ranks, and each rank has 4 cards (one of each suit).
• Therefore, there are (13 choose 2) = 78 possible pocket pairs.

So the probability of being dealt a pocket pair is 78/1326, or approximately 5.9%.

Poker Hand Win Probability

The probability of winning a hand in poker is determined by the strength of your hand and the number of opponents you are playing against. The more opponents you have, the lower your chances of winning, and the stronger your hand, the higher your chances of winning.

Poker Probability Calculator

To make calculating your poker hand win probability easier, you can use a poker hand probability calculator. These calculators take into account the cards you hold, the community cards, and the number of opponents you are playing against to give you an accurate estimate of your chances of winning the hand.

Probability of One Pair in Poker

One of the most common poker hands is one pair, which consists of two cards of the same rank. The probability of getting one pair in a five-card poker hand is approximately 42.3%. However, the probability of getting one pair in a three-card poker hand is much higher, at 16.9%.

3 Card Poker Probability

In three-card poker, players are dealt three cards, and the goal is to have the highest-ranked hand possible. The probability of getting a straight flush, the highest-ranking hand in three-card poker, is approximately 0.22%. The probability of getting a pair, however, is much higher, at approximately 16.9%.

4 Card Poker Probability

Four-card poker is similar to three-card poker, but players are dealt four cards instead of three. The probability of getting a straight flush in four-card poker is approximately 0.02%, and the probability of getting a pair is approximately 28%.

5 Card Poker Probability

In five-card poker, players are dealt five cards, and the goal is to have the highest-ranked hand possible. The probability of getting a royal flush, the highest-ranking hand in five-card poker, is approximately 0.0032%. The probability of getting one pair, however, is much higher, at approximately 42.3%.

Full House Poker Probability

A full house is a hand that consists of three cards of one rank and two cards of another rank. The probability of getting a full house in a five-card poker hand is approximately 2.6%.

Poker Game Probability

The probability of winning a poker game depends on several factors, including the number of opponents, the strength of your hand, and the style of play. In general, the more opponents you have and the weaker your hand, the lower your chances of winning.

Poker Hand Probability Texas Holdem

Texas Holdem is one of the most popular variants of poker, and the probability of winning a hand in this game depends on the strength of your hand, the number of opponents, and the community cards. The probability of getting a pair in Texas Holdem is approximately 42.3%, and the probability of getting a full house is approximately 2.6%.

How to Calculate Poker Probability

To calculate your poker probability, you need to take into account your cards, the community cards, and the number of opponents you are playing against. You can then use mathematical formulas to determine your probability of winning the hand.

Examples of Poker Probabilities

Let’s understand poker with reference to probability in depth. 

Probability of Being Dealt Pocket Aces

Pocket Aces (two Aces as your starting hand) is the best possible starting hand in Texas Hold'em. The probability of being dealt Pocket Aces is:

• There are 52 cards in the deck.
• There are 4 Aces.
• The first card dealt can be any Ace (4/52).
• The second card dealt must be the other Ace (3/51).
• So the probability of being dealt Pocket Aces is (4/52) * (3/51), or approximately 0.45%.

Probability of Flopping a Flush Draw

A flush is a poker hand consisting of five cards of the same suit. To calculate the probability of flopping a flush draw (i.e. having four cards of the same suit and needing one more on the turn or river), you would do the following:

• There are 52 cards in the deck.
• There are 13 cards of each suit.
• To flop a flush draw, you need to be dealt two cards of the same suit (13/52 for the first card, and 12/51 for the second card).
• The probability of flopping a flush draw is therefore (13/52) * (12/51), or approximately 5.18%.

Probability of Making a Straight

A straight is a poker hand consisting of five cards in sequential order. To calculate the probability of making a straight, you would do the following:

• There are 52 cards in the deck.
• To make a straight, you need to have 5 consecutive cards.
• There are 10 possible starting hands for a straight (A-5, 2-6, 3-7, 4-8, 5-9, 6-10, 7-J, 8-Q, 9-K, 10-A).
• Each starting hand has four possible ways of completing the straight.
• So the total number of ways to make a straight is 40 (10 starting hands x 4 ways to complete each hand).
• The probability of making a straight is therefore 40/2,598,960, or approximately 0.00154%.
