Question 183472
 In a clinical trial, a drug used to reduce fever caused side effects in 2% of patients who took it. Three patients were selected at random. Find the probability that none of those patients had side effects.
------------
P(side effects) = 0.02
P(no side effects) = 0.98
------------------------------
P(no side effects for three patients) = (0.98)^3 = 0.941...
