Question

There are 10 boys trying out for the track team. Truman and Ryan are the two fastest runners. If the coach randomly picks two boys to run a sprint, what is the probability that he will pick Truman and then Ryan?

Answer 1

10 kids total

picking Truman would be 1 out of 10 or 1/10

then there would be 9 kids left so picking Ryan would be 1 out of 9 or 1/9

the probability of picking both would be 1/10 * 1/9 = 1/90
