a bag contains 3 green marbles, 2 yellow marbles, and 5 blue marbles. a marble is picked at random and replaced. a second marble is picked at random. what is the probability that the first marble is yellow and the second is not yellow.

Answer 1

It is replaced so the drawings are independent
10 marbles total
probability yellow = 2/10
probability not yellow = 8/10
product = 2/10 * 8/10

= 1/5 * 4/5
= 4/25
= 0.16
