Question

Find the value of each permutation.

$P(9,0)$

Short answer

The value of the given permutation is 1.

Step-by-step solution

Step 1. Given information.

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

Step 2. Determine the value of the permutation.

We know that,

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

The given permutation can be written as:

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

Step 3. Conclusion.

The value of the given permutation is 1.
