Question

A bag contains 7 green marbles, 9 red marbles, 10 orange marbles, 5 brown marbles, and 10 blue marbles. You choose a marble, replace it, and choose again. Find P(red, then blue).

Answer 1

To find the answer of this problem, you have to multiply the probability of choosing red by the probability of choosing blue.

P(red)= 9/41

(blue)=10/41

9/41 (10/41) = 0.0535

The probability is about 5.35%
