Chapter 7.2, Problem 57E
Canadians who visit the United Sates often buy liquor and cigarettes, which are much cheaper in the United Sates. However, there are limitations. Canadians visiting in the United Sates for more than 2 days are allowed to bring into Canada one bottle of liquor and one carton of cigarettes. A Canada customs agent has produced the following joint probability distribution of the number of bottles of liquor and the number of cartons of cigarettes imported by Canadians who have visited the United States for 2 or more days.
- a. Find the marginal probability distribution of the number of bottles imported.
- b. Find the marginal probability distribution of the number of cigarette cartons imported.
- c. Compute the mean and variance of the number of bottles imported.
- d. Compute the mean and variance of the number of cigarette cartons imported.

A large consumer goods company ran a television advertisement for one of its soap products. On the basis of a survey that was conducted, probabilities were
assigned to the following events.
B = individual purchased the product
S = individual recalls seeing the advertisement
BnS = individual purchased the product and recalls seeing the advertisement
The probabilities assigned were P(B) = 0.20, P(S) = 0.40, and P(BS) = 0.12.
a. What is the probability of an individual's purchasing the product given that the individual recalls seeing the advertisement (to 1 decimal)?
Does seeing the advertisement increase the probability that the individual will purchase the product?

Insurance: An insurance company sells a 1-year term life insurance policy to an 84-year-old man. The man pays a premium of $1600. If he dies within 1
year,
the company will pay $33,000 to his beneficiary. According to the U.S. Centers for Disease Control and Prevention, the probability that an 84-year-old man will
be alive 1 year later is 0.9537, Let X be the profit made by the insurance company.

- The probability that it will rain on any given day is 0.20, and the probability is independent from day to day. You are trying to decide whether or not to make a tee time tomorrow to play golf. This requires a commitment on your part of turning down, say, movie tickets in favor of playing golf. If you accept the tickets, you also make the commitment not to go golfing. There is a weather forecast that signals whether it will rain tomorrow or not. There is a 0.80 probability that it rains when there is a "rainy" forecast and a 0.125 probability of rain when there is a "sunny" forecast. The overall probability of getting a "rainy" forecast is 0.111. Assume you are risk neutral.
