Python | sympy.binomial() method
With the help of sympy.binomial() method, we can find the number of ways to choose k items from a set of n distinct items. It is also often written as nCk, and is pronounced “n choose k”.
Syntax: binomial(N, K)
N – It denotes the number of items to choose from.
K – It denotes the number of items to choose.
Returns: Returns the number of ways to choose K items from a set of N distinct items
N = 4, K = 2 N choose K : 6
N = A, K = B N choose K : binomial(A, B)
