Question

Please help! I tried 1/4 and its wrong.

The number of marbles of different colors stored in a hat is listed below:

8 red marbles
10 green marbles
6 blue marbles
Without looking in the hat, Tessa takes out a marble at random. She replaces the marble and then takes out another marble from the hat. What is the probability that Tessa takes out a blue marble in both draws?

fraction 1 over 16

fraction 1 over 12

fraction 1 over 4

fraction 1 over 2

Answer 1

1/16

Explanation:

Answer 2

Ok so on the first draw, 6/24 marbles are likely to be blue so there is 1/4 chance of obtaining blue originally. But, she puts it back and again it's 1/4 of obtaining the blue again. So 1/4 X1/4 = 1/16.
