A computer retail store has 14 personal computers in stock. A buyer wants to purchase 3 of them. Unknown to either the retail store or the buyer, 3 of the computers in stock have defective hard drives. Assume that the computers are selected at random. What is the probability that exactly one of the computers will be defective? What is the probability that at least one of the computers selected is defective? 3. The attempt at a solution - I'm at a loss on this problem. I've been able to work all the other problems from the homework, but I just can't seem to figure this one out. Can someone please help?
