Chapter 8.2, Problem 85E

Medicine. In order to test a new drug for adverse reactions, the drug was administered to $1,000$ test subjects with the following results: $60$ subjects reported that their only adverse reaction was

a loss of appetite, $90$ subjects reported that their only adverse reaction was a loss of sleep, and $800$ subjects reported no adverse reactions at all. If this drug is released for general use, what is the (empirical) probability that a person using the drug will suffer both a loss of appetite and a loss of sleep?
