Answer 1

Answer #1

Solution:

In the given problem, we have 7 horses running in a race.

We have to find the number of ways the first, second, and third places can be filled.

Since the order matters here, therefore, we have to use the permutation rule to find the number of possible ways.

Therefore, the number of ways we can have the first, second, and third-place finishers are 210
