Given:
Probability that he gets into NYPD is 0.60
Probability that he gets into CSI is 0.70
Probability that he gets into both is 0.40
Probability that he gets into ONLY NYPD? 0.60 - 0.40 = 0.20
Probability that he gets into ONLY CSI? 0.70 - 0.40 = 0.30
To determine the total cost of the books, multiply the amount per book with the number of books. In this example, each book costs one pound and ninety-five pence. Converting 95 pence to pound gives 0.95 pounds. Therefore, the cost of each book is 1.95 pounds. Multiply this amount by six, we get 11.7 pounds. Thus, six books cost 11 pounds and 70 pence.
