Frequently Asked Questions

A permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters.

The formula for permutations is nPr = n! / (n - r)!, where n is the total number of items and r is the number of items being arranged.

In permutations, the order of items is essential (like a lock code). In combinations, the order does not matter (like a fruit salad).
