(Answered) Public policy and political science during the cold war

Statistics

Public Policy and Political Science During the Cold War there were frequent radio tests of alert warnings. The regular program was interrupted and replaced by a long high-pitched signal. An announcer would break in with a message similar to, "This has been a test of the emergency broadcasting system.'' Suppose the time (in hours) between these tests had an exponential distribution with mean 24 hours.

a. If a test occurred at 6:00 a.m., what is the probability that another one would occur before 6:00 p.m.?

b. If a test occurred at 10:00 p.m., what is the probability that another one would not occur until after 6:00 a.m.?

c. If a test occurred at 9:00 a.m., what is the probability that the next test would occur between 12:00 p.m. and 1:00 p.m.?
