A bag contains green and yellow color tiles. You pick two tiles at random with out replacing the first one.
The probability that the first tile is yellow is 3/5.
------
The probability of drawing two yellow tiles is 12 to 35.
P(yellow and yellow) = P(y)*P(y|y)
12/35 = (3/5)*P(y|y)
P(y|y) = 12/21 = 4/7
------
Find the probability that the second tile you pick is yellow.
P(y|y) = 4/7
