A bag contains green and yellow color tiles. You pick 2 at random without replacing the first. The probability the first time is yellow is 3/5. The probability of drawing 2 yellow tiles is 12/35. Find the probability the second tile is yellow.
----------------
P(yellow | yellow) = [P(yellow and yellow)]/[P(yellow)]
= [12/35] / [3/5]
= [12/35]
= 4/7
