Question

Probability of picking 2 marbles without looking out of a bag containing 2 red marbles, 2 blue marbles, and 2 white marbles. What is the probability that you will choose a red marble and then a blue marble without replacing the red one?

Answer 1

Answer: 2/15

Explanation:

2 red

2 blue

2 white

6 total

2/6 chance of getting red (1/3)

2/5 chance of getting blue next

2/5*1/3 = 2/15

I think. Sorry if I’m wrong.
