WebOne could say that a permutation is an ordered combination. The number of permutations of n objects taken r at a time is determined by the following formula: P ( n, r) = n! ( n − r)! n! is read n factorial and means all numbers from 1 to n multiplied e.g. 5! = 5 ⋅ 4 ⋅ 3 ⋅ 2 ⋅ 1. This is read five factorial. 0! Webb) Permutation involves finding possible ways in which order/ arrangement matters. On the other hand, combination involves calculating the possible ways which order/arrangement does not matter. With this, we are able to differentiate the tasks/situations that involve permutation from those that involve combination.
