The value of the given permutation is 1.

See the step by step solution

## Step 1. Given information.

The given permutation is $P\left(9,0\right)$.

## Step 2. Determine the value of the permutation.

We know that,

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

The given permutation can be written as:

$\begin{array}{rcl}P\left(9,0\right)& =& \frac{9!}{\left(9-0\right)!}\\ & =& \frac{9!}{9!}\\ & =& 1\end{array}$

## Step 3. Conclusion.

The value of the given permutation is 1.
