Answer to Problem 11RE

The value of $P\left(8,3\right)$ is $336$ .

Explanation of Solution

Given: $P\left(8,3\right)$ .

The value of $P\left(8,3\right)$ is calculated as,

  $\begin{array}{c}P\left(n,r\right)=n\left(n-1\right)\mathrm{....}\left(n-r+1\right)\\ P\left(8,3\right)=8\left(8-1\right)\mathrm{...}\left(8-3+1\right)\\ =8\cdot 7\cdot 6\\ =336\end{array}$
