A certain type of toy Baal is either red or green and is either striped or nor striped. If a ball is randomly selected, the probability that it is red(R) is .60, the probability it is striped (S) is .30, and the probability that it is red and striped is .20. Find the conditional probability that it is striped. Give it as a simple fraction.

Solution
Let
R = red
G= green
S = striped
Thus,
P(S|R) = P(S n R) / P(R) = 0.20/0.60 = 1/3 [ANSWER]
