Question

there are 18 skaters competing in the competition. how many ways can they win the gold, silver, and bronze medal? 54 283 816 2368 4896

Explanation:

Step1: Choose permutation formula

Order matters (gold≠silver≠bronze), so use $P(n,k)=\frac{n!}{(n-k)!}$ where $n=18$, $k=3$.

Step2: Calculate the permutation

$P(18,3)=18×17×16=4896$.

Answer:

C. 4896
