A permutation is defined as an arrangement in a definite order of a number of objects taken some or all at a time. Counting permutations are merely counting the number of ways in which some or all objects at a time are rearranged. The convenient expression to denote permutation is defined as “ nP”.

The permutation formula is given by,

Pr = n!/(n-r)! ; 0 ≤ r ≤ n
