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

 x 1 2 3 4 5 6 p(x) 0.3 0.25 0.2 0.1 0.1 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?

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

A tidal wave or tsunami is usually the result of an earthquake in the Pacific Rim, often 1000 or more miles from Hawaii. Tsunamis are rare but dangerous. Many tsunamis are small and do little damage. However, a tsunami nine meters or higher is very dangerous Civil Defense authorities sound an alarm telling people near the beach to go to higher ground. About 30% of all recorded tsunamis have been nne meters or higher t You are writing a report...
