Suppose that the probability function in the table below reflects the possible lifetimes (in months after emergence) for fruit flies. Let the random variable X measure fruit fly lifetimes (in months). Fruit fly lifetimes (in months) 3 4 6 p(x) 0.30 ? 0.20 0.10 0.10 0.05 (a) What proportion of fruit flies die in their second month? Enter the exact answer. P(X = 2) = i eTextbook and Media (b) What is the probability that a fruit fly lives more than four months? Enter the exact answer. P(more than four months) = i eTextbook and Media (c) What is the mean lifetime for a fruit fly? Enter the exact answer. months = 1
