For example, let us consider a permutation from 1 to 5 P = [2 4 1 5 3] This representation directly indicates the position of each number. i.e 2 is first, 4 is second and so on. Alternatively, this can also be represented in inverse permutation form. A = [3 1 5 2 4]
WebNCR formula is used to find the number of ways where r objects chosen from n objects and the order is not important. It is represented in the following way. nCr = nP r r! = n! r!(n−r)! n C r = n P r r! = n! r! ( n − r)! Here, n is the total number of things. r is the number of things to be chosen out of n things.
