A doctor may administer drug A or drug B to her/his patients. Drug A is used on all
patients except for the 10 % that show an allergic reaction to the drug. Ninety percent of
the patients treated with drug A recover, while 70% of the patients treated with Drug B
recover. a) Find the probability that a person will be treated with Drug A and will
recover. b) a person will be treated with Drug B and will not recover

The summer monsoon rains in a country follow approximately a Normal distribution with mean 854 millimeters (mm) of rainfall and standard deviation 87 mm.
(b) "Normal rainfall" means within 20% of the long-term average, or between 683 mm and 1025 mm. In what percent of all years is the rainfall normal?
