A magazine published the results of an extensive investigation of broiler chickens purchased from food stores in 23 regions. Tests for bacteria in the meat showed that 61% of the chickens were contaminated with campylobacter, 19% with salmonella, and 6% with both.
a) What's the probability that a tested chicken was not contaminated with either kind of bacteria?
b) Are contamination with the two kinds of bacteria disjoint? Explain.
c) Are contamination with the two kinds of bacteria independent? Explain.

Comb shape in chickens results from the epistatic interaction of
two genes. The first gene (T/t) affects the basic shape of the comb
such that: TT and Tt results in a walnut (normal) comb while tt
results in pea comb. The recessive allele (r) of a second gene
(R/r) modifies the first gene, but the dominant allele (R) does
not. Thus RR and Rr has no effect on comb shape, while rr paired TT
or Tt produces a rose comb...
