If the demand were predictable, would you want to use a probability law todescribe it? Under what circumstances might the use of a probability model of demand be justified even if the demand could be predicted exactly?
15. A city mayor decides to construct a new bridge over the major river in the town. The estimated life of
such a structure will be 20 years. There is a 70% probability that the total initial costs (consulting fees and
construction) will be $800,000 and a 30% probability that such costs would be $1 million. There is 100%
probability that the maintenance costs would be $30,000 every 5 years. How much money should the city
borrow now in order to carry out the entire project including maintenance? The interest rate is 5%.

Based on your work managing the project, you know that each team has about a 75% chance of meeting the deadline. a. The probability that your firm will complete the project by the end of the year is b. Suppose that before you calculate the probability of completing the project, you walk into a weekly status meeting with the CEO. When she asks you for your "gut feeling" about the probability of finishing the project by the end of the year, you respond with an answer that exhibits the anchoring bias. Your response will likely be, "About 70%." "About 90%." "About 25%."arrow_forward
