The following table summarizes 100 deceased beetles under autolysis (the destruction of a cell after its death by the action of its own enzymes) and putrefaction (decomposition of organic matter, especially protein, by microorganisms. resulting in production of foul-smelling matter): If the autolysis of a sample is high, what is the probability that the putrefaction is low? If the putrefaction of a sample is high, what is the probability that the autolysis is high? If the putrefaction of a sample is low, what is the probability that the autolysis is low?

Solution

a)

P(pur is low|aut is high) = 18/(14+18) = 0.5625 [answer]

********

b)

P(aut is high|pur is high) = 14/(14+59) = 0.191780822 [answer]

********

c)

P(aut is low|pur is low) = 9/(18+9) = 0.3333333 [answer]
