Work Step by Step

Use the formula of permutation: $_{n}$P$_{r}$=$\frac{n!}{(n-r)!}$. Plug in 11 for N and 0 for R: $_{n}$P$_{r}$=$\frac{n!}{(n-r)!}$ $_{11}$P$_{0}$=$\frac{11!}{(11-0)!}$ -simplify- $_{11}$P$_{0}$=$\frac{11!}{11!}$ -write using factorial- $_{11}$P$_{0}$=$\frac{1}{1}$ -simplify- $_{11}$P$_{0}$=1
