Question

A helicopter and a plane can make a safe landing if at least half of its engines are working properly. Suppose that engine failures are independent events. Determine whether a two engine helicopter or a four engine plane is safer if the chance that an engine fails is 1 in 100?

Answer 1

Answer:

I think the probability of two engines failing would be the same for either aircraft. In the instance that does happen, the helicopter doesn't fly at all and the airplane does.

I say the airplane is safer.
