Question

There are 4 green marbles, 3 red marbles, and 7 yellow marbles in a bag. What is the probability of drawing 1st a green and 2nd a green marbles with replacement.

Answer 1

4/14 x 4/14 x 4/14 x 4/14 = 256/38416

Explanation:

There are 4 green marbles

3 red marbles

7 yellow marbles

Altogether = 4 + 3 + 7 = 14

Probability of picking a green marble 1st = 4/14

Probability of picking a green marble 2nd = 4/14

and you still have 2 more green marbles in the bag, so it will look like this:

4/14 x 4/14 x 4/14 x 4/14 = 256/38416
