Question

A jar of marbles contains 7 blue marbles, 12 yellow marbles, 8 green marbles, and 5 red marbles. Use this information to answer the following questions. Jenny chooses a marble at random from the jar. After replacing it, she chooses a second marble. What is the probability Jenny chooses a green marble then a yellow marble?
Answer choices:
5/8

3/31

3/32

5/16

Answer 1

Total marbles = 7 + 12 + 8 + 5 = 32
Green marbles = 8
Yellow marbles = 12

P(green ,then yellow) = (8/32)(12/32) = 3/32

Answer: The probability is 3/32
