Question

There are 5 red marbles, 15 blue marbles, and 5 green marbles in a bag. If you reach in and randon

without replacing the first, what is the probability that both will be blue?

Answer 1

Likely

Explanation:

It is very likely that you will pick a blue marble because the bag is mostly filled with blue marbles so even if it is random it is more probable

Answer 2

7/20 is the probability that both marbles drawn will be blue.

Explanation:

25 marbles in all.

After you take the first one out, there are 24 marbles left, and fourteen of them are blue.

15/25 x 14/24 = 210/600.

Reduce that to it's simplest form and you get 7/20.

Good luck, I hope this helps.
