## What is Keno?

Keno is a lottery-style game in which players can win a large amount of money, and is similar to bingo in many ways. Players are asked to pick anywhere from one to fifteen numbers, out of a selection of between 1 and 80. The player then waits while the numbers are drawn, and the more numbers they have chosen that match the ones drawn, the more they win.

## How Many Combinations are There in Keno?

The number of combinations in Keno is enormous. Depending on how many numbers you pick, the number of possible combinations can range from a few hundred to millions. To put it into perspective, if you choose 15 numbers from the 80 available, there are over 30 million different possible combinations that could be drawn.

## How to Calculate the Number of Combinations in Keno?

The number of combinations in Keno can be calculated using a mathematical formula known as the Binomial Coefficient. This formula is used to calculate the number of ways in which a certain number of items can be chosen from a larger set.

### What is the Binomial Coefficient?

The Binomial Coefficient is a mathematical formula used to calculate the number of combinations in a set of objects. It is represented as **C(n,r)**, where **n** is the total number of objects, and **r** is the number of objects chosen.

### How to Use the Binomial Coefficient to Calculate Combinations in Keno?

To calculate the number of combinations in Keno, simply plug the two numbers into the formula. For example, if you choose 15 numbers from the 80 available, the formula would look like this:

**C(80,15)**. This formula can also be used to calculate the number of combinations for any number of chosen numbers from 1 to 80.
