In how many different ways can 7 bicycles be parked if there are 5 available parking spaces?

P(n,r) = n! / (n - r)!

P(7,5) = 7! / (7 - 5)!

P(7,5) = 7! / 2!

P(7,5) = 7 • 6 • 5 • 4 • 3 • 2! / 2!

P(7,5) = 7 • 6 • 5 • 4 • 3

P(7,5) = 2520 ways

In a certain general assembly, three major prizes are at the stake. In how many ways can the first second and third prizes be drawn from a box containing 20 names?

P(n,r) = n! / (n - r)!

P(20,3) = 20! / (20 - 3)!

P(20,3) = 20! / 17!

P(20,3) = 20 • 19 • 18 • 17! / 17!

P(20,3) = 20 • 19 • 18

P(20,3) = 6840 ways
