Question 951079: Bills of Four Denominations Duc Tran’s wallet contains 8 bills of the following denominations: four $5 bills, two $10 bills, one $20 bill, and one $50 bill. If Duc selects two bills at random, determine the probability that he selects two $5 bills. Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! Duc has a total of 8 bills and four are $5, so for his first selection the odds are 4 in 8 he will choose a $5 bill. If he chooses the first $5 bill, there are 7 total bills remaining with 3 $5 bills, so there is a 3 in 7 chance he will choose the second $5 bill. Overall: = ANSWER: There is a 3 in 14 chance that Duc will select two $5 bills.
