18) A recent study indicates that Pepsi-Cola has a market
share of 33.2% (versus 40.9% for Coca- Cola). A marketing research
firm wants to conduct a new taste test for which it needs Pepsi
drinkers. Potential participants for the test are selected by
random screening of soft drink users to find Pepsi drinkers.
(a) What is the probability that the first randomly selected
drinker qualifies as a Pepsi- Cola drinker?
(b) What is the probability that two soft drink users will
have to be interviewed to find the first Pepsi drinker?
