Question

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag. What is the theoretical probability of randomly drawing a red marble and then a green marble? 10% 68% 9.6% 17%

Answer 1

10%

-------------------------------------------------

Total marbles = 5 + 8 + 12 = 25

P(red then green) = (5/25)(12/24) = 1/10

1/10 = 0.1 = 10%
