Americans drink a lot of coffee, and they put all sorts of extras into their coffee to enhance the drink, including flavor shots and flavored creams. Research data indicates that 62% of all coffee drinkers put creamer in their coffee.52 Of those people who use creamer, 40% say they would drink more coffee if their preferred flavors were offered. Suppose a coffee drinker is selected at random.
a. Suppose the coffee drinker uses creamer. What is the probability that he would not drink more even if his preferred flavor were offered?
b. What is the probability that the coffee drinker uses creamer and would drink more if his preferred flavour were offered?
c. Suppose three coffee drinkers are selected at random. What is the probability that exactly one uses creamer?
