Summary – Permutation Formula
The permutation formula helps you calculate the number of unique arrangements (order matters) for a selection of items from a larger set. It is denoted by nPr, where n is the total number of items and r is the number of items you are choosing to arrange. The formula is nPr = n! / (n – r)!, where n! represents n factorial (n multiplied by all the positive integers less than n).

Permutation Formula
Permutation Formula: In mathematics, permutation relates to the method of organizing all the members of a group into some series or design. In further terms, if the group is already completed, then the redirecting of its components is called the method of permuting. Permutations take place, in better or slightly effective methods, in almost every district of mathematics. They usually occur when different directions on detailed restricted sites are monitored.
