What is Meant by N Choose K?

In Mathematics, the term combination refers to the selection of an object from the collection, where the order of selection does not matter. Let assume that, if the set has “n” objects, then the number of “k” combinations of the object is equal to the binomial coefficient. The binomial coefficient of n choose k formula in the factorial form is written as follows:

C(n, k)= n!/[k!(n-k)!]


“n” is the total number of objects

“k” is the number of selected objects
