Question

Dr. Emmett Brown has a bag of M&Ms. He has 7 green M&Ms, 12 brown M&Ms, 3 blue M&Ms, and 5 red M&Ms.

What is the probability that Emmett selects a blue M&M and another blue M&M without replacement?

Answer 1

There are 27 total M and M in the bag and 3 blues.

The probability of selecting a blue on the first draw is 3/27 leaving 26 total and 2 blues.

The probability of selecting a blue on the second draw is 2/26.

The probability of both events occurring (picking a blue on both draws) = 3/27 * 2/26 = 0.0085
