Early in 2010, Consumer Reports published the results of an extensive investigation of broiled chickens purchased from food stores in 23 states. Tests for bacteria in the meat showed that 62% of the chickens were contaminated with campylobacter, 14% with salmonella, and 9% with both. (a) What is the probability that a tested chicken was not contaminated with either kind of bacteria? (b) Are contamination with the two kind of bacteria disjoint events? Explain
