    the two yellow shirts are not enough for three days.. so we are finding the probability that she wear a red shirt each day on monday the probability that she wear a red shirt is 3/5 (since we have 3 red shirts out of a total of 5 shirts) on tuesday we have only 4 shirts left.. 2 of them are red so the probability that she wears a red shirt on tuesday is 2/4 on wednesday 3 shirts are left.. only one of the is red so the probability thet she wears a red shirt on wednesday is 1/3 now multiply them the answer is (3/5)*(2/4)*(1/3)
