Work Step by Step

Use the formula of permutation: $_{n}$P$_{y}$=$\frac{n!}{(n-r)!}$.plug in 9 for N and 5 for R: $_{n}$P$_{y}$=$\frac{n!}{(n-r)!}$ $_{9}$P$_{5}$=$\frac{9!}{(9-5)!}$ -simplify- $_{9}$P$_{5}$=$\frac{9!}{(4)!}$ -write using factorial- $_{9}$P$_{5}$=$\frac{9*8*7*6*5*4*3*2*1}{4 *3*2*1}$ -simplify- $_{9}$P$_{5}$=15120
