Question

Suppose that in a certain part of the world, in any 50-year period the probability of a major plague is .39, the probability of a major famine is .52, and the probability of both a plague and a famine is .15. what is the probability of a famine given that there is a plague?

Answer 1

Answer: P(famine | plague) = P(famine and plague) / P(plague) = (0.15) / (0.39) = 0.385
