* (n – r)!, where n represents the number of items, and r represents the number of items being chosen at a time..
How do you calculate permutations?
The number of permutations of n objects taken r at a time is determined by the following formula: P(n,r)=n! (n−r)! A code have 4 digits in a specific order, the digits are between 0-9.
