6. A study of major flash floods that occurred over the last 15 years indicates that the probability that a flash flood warning will be issued is 0.5 and that the probability of darn failure during the flood is 0.33. The probability of dam failure given that a warning is issued is 0.17. Find the probability that a flash flood warning will be issued and a darn failure will occur.

Solution

Note that

P(warning and failure) = P(warning) P(failure|warning)

Thus,

P(warning and failure) = 0.5(0.17) = 0.085 [ANSWER]
