Kim has 3 blue sweaters, 2 red sweaters, and 5 white sweaters in a dresser drawer. If she selects 3 sweaters at random with replacement, what is the probability she will select a red one first, white second, and blue third?

3 blue, 2 red, 5 white ... total of 10 sweaters

probability that red is picked first : 2/10 reduces to 1/5

replace

probability of second pick being white : 5/10 reduces to 1/2

replace

probability of third pick being blue : 3/10

probability of all of this happening : 1/5 * 1/2 * 3/10 = 3/100 <==
