What is r in permutation formula?
The formula for a permutation is: P(n,r) = n! / (n-r)! where. n = total items in the set; r = items taken for the permutation; “!” denotes factorial.
How do you calculate permutations?

How did you calculate the different permutations?
Permutation Notation When writing permutations, we use the notation nPr, where n represents the number of items to choose from, P stands for permutation and r stands for how many items you are choosing. To calculate the permutation using this formula, you would use nPr = n! / (n – r)!.
