Explanation of Solution
Given information:
8 sprinters have qualified for the finals in the 100 meter dash at the NCAA national track meet.
Calculation:
Assume there are 8 sprinters qualified for final round in a competition, also assume that only 3 prices are given, and so find the number of ways of selection of first 3 among 8, since it is a arrangement of 3 from 8 people, therefore,
Since the number of permutations of
Here
So, the number of permutation of six sprinters taken three at a time is
