Question

A bag contains 5 blue marbles, 6 red marbles, and 9 green marbles. Two

marbles are drawn at random, one at a time. What is the probability of
selecting a green marble and then, without replacing it, a red marble?​

Answer 1

27/190

Explanation:

5+6+9 = 20

9/20 × 6/19 = 27/190 = 0.142

Answer 2

3/28

Explanation:

Probability of getting a blue marble- 5/20

Probability of getting a red marble- 6/19

5/20 x 6/19= 3/38
