Answer 1

Jose is paying for a ten dollar meal using bills in his wallet. He has five one dollar bills and four five dollar bills. If he selects two bills at random, one at a time from his wallet, without replacement, what is the probability that he will choose two five dollar bills to pay for the meal? Show your work.

Answer 2

total he has 5+4 =9
so prob
picking one five dollar bills first =4/9 and since replacement is not done so second time it is 3/8
hence reqd = 4/9 *3/8 =1/6
