Permutation Formula A permutation of n different objects taken r at a time where r ≤ n is given as P ( n, r) = n! ( n − r)! Derivation WebSo, the permutations will have 6 times as many possibilities. In fact there is an easy way to work out how many ways "1 2 3" could be placed in order, and we have already talked about it. The answer is: 3! = 3 × 2 × 1 = 6 (Another example: 4 things can be placed in 4! = 4 × 3 × 2 × 1 = 24 different ways, try it for yourself!)
