Binomial coefficient

Binomial coefficient is a mathematical term that represents the number of possible combinations or ways to choose k objects from a set of n distinct objects.
It is denoted by the symbol "n choose k" or "C(n, k)" and can be calculated using the following formula:

C(n, k) = n! / (k! * (n - k)!)

where "!" denotes the factorial function. The factorial of a non-negative integer n is the product of all positive integers up to n, and is denoted by "n!".
