A soccer coach must choose 3 out of 10 players to kick tie-breaking penalty shots. Assuming the coach must choose the order of the 3 players, how many different arrangements does she have available?

Solution

Numbers of different arrangements does she have available = ¹⁰P₃ = 10!/(10 - 3)! = 10! = 7! (option C)
