Answer:
Number of different ways they can finish first, second and third = 1320
Step-by-step explanation:
Number of total runners in a cross country race = 12
Number of ways in which we can select the racer who finishes first = 12
Number of ways in which we can select the racer who finishes second = 11
Number of ways in which we can select the racer who finishes third = 10
Now, we need to find the different ways they can finish first, second and third.
So, Required number of total ways = 12 × 11 × 10
= 1320
Thus, Number of different ways they can finish first, second and third = 1320
