A certain drug causes kidney damage in 1% of the patients. Suppose that the drug is to be tested on "n" patients, and let "E" represent the event that kidney damage occurs in one or more of the patients. The probability Pr {E} is useful in establishing criteria for drug safety.
a) Fnd Pr {E} for n = 100
b) How large must "n" be in order for Pr {E} to exceed 0.95?
