# How Many Poker Hand Possibilities Are There?

Poker is one of the most popular card games in the world. It is played by millions of people worldwide, both professionally and for fun.

One of the fascinating aspects of poker is the sheer number of different hand possibilities that exist. In this article, we will explore just how many poker hand possibilities there are.

To begin with, let’s define what we mean by a “hand” in poker. A hand consists of five cards, which can be any combination of cards from a standard deck of 52 cards. There are four suits in a deck – clubs, diamonds, hearts, and spades – and each suit has 13 cards: Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack (J), Queen (Q), and King (K).

With those basic parameters in mind – five cards drawn from a deck with four suits and thirteen ranks – we can begin to calculate the number of possible hand combinations.

The first thing to consider is the order in which the cards are drawn. In poker, the order doesn’t matter – a hand consisting of Ace-King-Queen-Jack-10 is considered equivalent to one consisting of King-Ace-Queen-10-Jack. This means that we need to use a combination formula rather than a permutation formula to calculate the number of possible hands.

The combination formula tells us how many ways we can choose k items from n items without regard to order. In this case, we want to choose five cards from a deck containing 52 cards. So our formula looks like this:

52C5 = (52!)/(5!47!)

That may look like an intimidating equation at first glance but don’t worry; there’s an easier way to think about it.

Imagine you have a bag containing all 52 cards from a deck. You reach into the bag and pull out one card.

There are 52 cards to choose from, so you have a 1/52 chance of picking any particular card. You put that card aside and repeat the process four more times, each time choosing from the remaining cards in the bag.

PRO TIP:There are over 2.5 million possible poker hands, with the exact number dependent on the specific game being played. The most common game is Texas Hold’em, which has 169 unique two-card starting hands and 1,326 possible five-card hands.

The probability of drawing any particular five-card hand is simply the product of the probabilities of each individual card being drawn. So the probability of drawing a specific hand like Ace-King-Queen-Jack-10 is:

(4/52) x (4/51) x (4/50) x (4/49) x (4/48)

The first factor, 4/52, represents the probability of drawing an Ace on the first draw – since there are four Aces in the deck and a total of 52 cards, your chance of drawing an Ace on your first draw is 4 in 52 or 1 in 13.

The second factor, 4/51, represents the probability of drawing a King on your second draw – since you’ve already drawn one card and there are only three Kings left in the deck, your chance of drawing a King on your second draw is 3 in 51, which simplifies to 4 in 68.

And so on for each subsequent draw. Multiplying all these probabilities together gives us the overall probability of drawing that specific hand – which turns out to be approximately 0.000240096 percent.

So how many different possible hands are there? We can use our combination formula to figure that out:

52C5 = (52!)/(5!47!) = (52x51x50x49x48)/(5x4x3x2x1) = 2,598,960

That’s right – there are over two and a half million possible five-card hands in poker! And remember, this calculation doesn’t even take into account factors like suits or card rankings – it’s just the number of possible combinations of five cards drawn from a standard deck.

To put that number in perspective, consider this: if you were to play one hand of poker every second, without ever repeating a hand, it would take you over 82 years to play through all the possible combinations!

In conclusion, the sheer number of possible hand combinations in poker is truly staggering. With over two and a half million different hands, there’s always something new to discover and explore in this endlessly fascinating game. Whether you’re a seasoned pro or just starting out, knowing how many possible hands there are can help you appreciate the complexity and depth of this timeless card game.
