a. Assuming the common-shock failure rate, \mu _(z), is 0dots
i. Calculate the probability at least one engine is still running at the end of a 6-
hour trans-Atlantic flight.
ii. Calculate the probability neither engine is still running at the end of a 6-hour
trans-Atlantic flight (as if you didn't know that was coming).
b. Trans-Atlantic flights are not without other perils (e.g., storms, terrorism, sparrows).

i. Calculate the probability at least one engine is still running at the end of a 6-
hour trans-Atlantic flight.
ii. Calculate the probability neither engine is still running at the end of a 6-hour
trans-Atlantic flight (as if you didn't know that was coming again).
iii. Calculate the probability that engine A is running, but engine B is not.
iv. Calculate the net single premium of an insurance product that pays $500,000 in
the event of a plane crash due to both engines failing. Assume the discount rate
is 0%.
