Bag of Toy Cars

Gilligan has a bag of toy cars. He has 4 red cars, 5 blue cars and 6 pink cars. There are 15 cars in total. What is the probability (with replacement) of randomly selecting a red car, a blue car and a pink car in that order?

Let me see.

I want P(red, blue, pink).

A = probability of selecting red car.

B = probability of selecting blue car.

C = probability of selecting pink car.

P(A) = 4/15

P(B) = 5/15

P(C) = 6/15

P(A, B, C) = P(A) • P(B) • P(C)

P(A, B, C) = (4/15) • (5/15) • (6/15)

Is this correct?

Beautiful.
