$\frac{n!}{(n-r)!}$

Step-by-step explanation:

Permutation is a way of arranging the elements of a set into a order or a sequence . Here order matters.

The number of permutations of n things taken r at a time is given by the following formula:

$^nP_r=\frac{n!}{(n-r)!}$

Therefore, the formula for the number of permutations of n things taken r at a time is $\frac{n!}{(n-r)!}$
