The amount of cosmic radiation to which a person is exposed while flying by jet across the United States is a random variable having a normal (Gaussian) distribution with average u = 4.35 mrem and o = 0.59 mrem of radiation. Find the probabilities that a person on such a flight will be exposed to
a. more than 5 mrem of cosmic radiation
b. between 3 and 4 mrem of cosmic radiation
