Assume the box contains 7 balls:

3 red, 2 blue, and 2 yellow. A ball is drawn and its

color noted. If the ball is yellow, it is replaced; otherwise, it is not.

A second ball is then drawn and its color is noted.

What is the probability that the first ball was yellow, given that the

second was red?
