For example, with four-digit PINs, each digit can range from 0 to 9, giving us 10 possibilities for each digit.
What is nPr formula?
Permutation: nPr represents the probability of selecting an ordered set of ‘r’ objects from a group of ‘n’ number of objects. The order of objects matters in case of permutation. The formula to find nPr is given by: nPr = n!/(n-r)! … nCr = n!/[r!
