Answer:
210
Step-by-step explanation:
We are arranging the first 3 horses that finishes out of 7 horses.
It's represented as 7P3; P- permutation [ arrangements]
7P3= 7!/ (7-3)!
= 7!/ 4!
= 7* 6* 5* 4! / 4! = 210
Answer:
There are 8 horses, the number of ways that first 3 finishers turn out is permutation with n = 8, k = 3.
N = 8P3 = 8!/(8 - 3)! = 8 x 7 x 6 = 336 ways
=> Option D is correct
Hope this helps!
