Tim and Sasha have a bag containing 7 red marbles, 3 blue marbles, 6 white marbles, and 4 yellow marbles. Tim reaches in, without looking, pulls out a marble, records the color, and then puts the marble back.Sasha then does the same thing.
What is the probability that Tim and Sasha each drew either a blue marble or a yellow marble?
That would be the product of Tim getting one of those colors, and then Sasha doing the same.
Out of 20 marbles, 7 are blue or yellow.
The answer is therefore (7/20)^2 = 49/400
This is not an algebra question.
