Question

More Fruit Fly Lifetimes

Suppose that the probability function in the table below reflects the possible lifetimes (in months after emergence) for fruit flies.

Fruit fly lifetimes (in months)

x	1	2	3	4	5	6
p(x)	0.30	0.25	0.20	0.10	0.10	0.05

(a) If we know a fruit fly died before the end of its second month, what is the probability it died in its first month?

Round your answer to two decimal places.

(b) If a fruit fly makes it past its second month, what is the probability it will live more than four months?

Round your answer to two decimal places.
