What is permutation?

The formula for permutation is given as:

Permutation = $\frac{n!}{n - r!}$

Where:

• n is the total number of objects = 9
• r is the number selected = 3

Substitute into the formula

Permutation = $\frac{9!}{9 - 3!}$

P( 9, 3) = $\frac{9!}{6!}$

P( 9, 3) = $\frac{362880}{720}$

P( 9, 3) = 504 ways

Thus, the number of ways of she can do it is 504 ways
