Usually, the number of permutation of n items chosen k at a time is:  A permutation is an arrangement of objects, without repetition, and order being all the permutations, you could use the formula for the number of permutations. P( n, r) or nP r is read as “the permutation of n things taken r at a time.” equation. If any of the objects in a permutation are repeats, a different formula is used.

Permutation formula

is defined to equal 1. For example, using this formula, the number of permutations of five objects taken two at a time is The formula for permutation is n P r = n! /(n-r)! The formula for combination is. n C r = n!/[r!(n-r)!] One 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)!
