What are the odds of a royal flush? This is a question that many poker players have asked themselves at one card game or another. The answer, however, is not as straightforward as you might think.

Read on to find out the odds of a royal flush.

# Probability of a Royal Flush in Poker

It seems like it will only take a few minutes for a royal flush to appear in any poker movie. This is a poker hand with a very specific structure: the ten and jack, queen, queen, king, and ace. This hand is usually dealt to the hero of the movie and is then revealed dramatically.

A royal flush is the highest-ranked hand in poker. It is very difficult to get a royal flush because of the requirements.

## Basic Assumptions & Probability

There are many ways to play poker. We will assume that a player is dealt five cards using a 52-card deck. The cards dealt are not wild and the player keeps all the cards.

Two numbers are required to calculate the probability of a royal flush.

- The total number of possible poker hands.
- The number of possible ways a royal flush could be dealt.

Knowing these numbers will allow us to calculate the probability of getting dealt a royal flush. Simply divide the second number by 1.

## Number of Poker Hands

To calculate the number of hands in poker, you can use some of the combinatorics techniques. It is important to remember that the order in the cards is irrelevant. Because the order doesn’t matter, each hand can be a combination of five cards out of 52.

The formula for combinations is used to determine the number of *C* ( 52, 5) possible hands.

The probability of getting dealt a royal flush depends on how many royal flushes you have divided by the total poker hands. Now, we divide the numbers and find

A probability this small can be difficult to grasp, much like very large numbers. This number can be put in perspective by asking how long it would take for 649,740 hands to complete. If you played 20 hands of poker per night, this would be only 7300 hands per year.

In 89 years, you can expect to see only one royal flush. This hand is not as common, despite what the movies might have us believe.
