In how many ways can 8 different trophies be arranged in a straight row in a showcase?

Answer and explanation

Correct answer: 40320

The governing idea is the permutation of distinct objects in a line. Since all 8 trophies are different and every trophy must be displayed, the first place has 8 choices, the next has 7, and the number of choices continues down to 1. Hence the total is 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 8! = 40,320. Therefore, option A is correct. The number 5,040 equals 7!, so it omits one factor of 8. The number 720 equals 6!, and 64 is merely 8²; neither accounts for the successive choices created by arranging all eight distinct trophies. Because the trophies form a straight row, this is not a circular permutation.
