Refer to the Image Power Green Brands Survey of international consumers, Exercise 3.4 (p. 84). Recall that a “green” product is one built from recycled materials that has minimal impact on the environment. The reasons why a consumer identifies a product as green are summarized in the next table. Consider interviewing consumers, at random. Let Y represent the number of consumers who must be interviewed until one indicates something other than information given directly on the product’s label or packaging as the reason a product is green.
a. Give a formula for the probability distribution of Y.
b. What is E(Y)? Interpret the result.
c. Find P(Y = 1).
d. Find P(Y >2).
