Question: The probability that a randomly selected American adult belongs to the American Automobile Association (AAA) is = .10 (10%), and the probability that that person belongs to the American Association of Retired Persons (AARP) is = .11 (11%) (Krantz, 1992, p. 175). What assumption would we have to make in order to use Rule 3 to conclude that the probability that a person belongs to both is (.10) x (.11) = .011? Do you think that assumption holds in this case? Explain.
