Quizplus · Accepted Answer

Permutations consider the order of selection, whereas combinations do not. When selecting 4 items from N without repetition, the number of permutations is N!/(N-4)!, and the number of combinations is N!/[4!(N-4)!]. The ratio of permutations to combinations is therefore 4! = 24, meaning there are 24 times as many permutations as combinations.
