Mary will miss an important TV program while taking his statistics exam, so he sets both his VCRs to record it. The first one records 70% of the time, and the second one records 60% of the time. What is the probability that he gets home after the exam and finds? We assume that events A and B are independent, so with P(A) = .7 and P(B) = .6 and their set complements Ac and Bc occurring with probabilities .3 and .4 respectively, we have: a) No copies of his program? b) One copy of his program? c) Two copies of his program? d)Good grief, a VCR? What’s that?
