$P\left(8,3\right)$

To determine

To find: The value of each permutation.

Answer to Problem 14AYU

336

Explanation of Solution

Given:

$P\left(8,3\right)$

Formula used:

$P\left(n,r\right)=\frac{n!}{\left(n-r\right)!}$

Calculation:

$P\left(n,r\right)=\frac{n!}{\left(n-r\right)!}$

$P\left(8,3\right)=\frac{8!}{\left(8-3\right)!}$

$P\left(8,3\right)=\frac{8!}{5!}=8*7*6*5!/5!$

$P\left(8,3\right)=336$
