A company's annual report includes comparative statements for several years

Wurst & Wurst is the accounting firm that has been used by the Intercontinental Bank for over twenty years. Ben approached Alfred, a Wurst partner, at a cocktail party. Ben asked about the Bank's stability. Although Alfred knew that the bank's stock was

overvalued because of some loans to third world countries, he felt a considerable amount of loyalty to the bank for being a good customer of his accounting firm. Alfred told Ben that Wurst had just finished an audit of the bank, and that the bank was as sound as the Rock of Gibraltar. The next day Ben bought 1,000 shares of Intercontinental. One month later, the bank's losses became the subject of a major financial scandal. Ben is angry and wants to sue. Does Ben have a case?

The Harbour Island Ferry leaves on the hour and at 15-minute intervals. The time, x, it takes John to drive from his house to the ferry has a uniform distribution with x between 10 and 20 minutes. One morning John leaves his house at precisely 8:00 A.M

a. What is the probability John will wait less than 5 minutes for the ferry? b. What is the probability John will wait less than 10 minutes for the ferry? c. What is the probability John will wait less than 15 minutes for the ferry? d. What is the probability John will not have to wait for the ferry? e. Suppose John leaves at 8:05 A.M. What is the probability John will wait (1) less than 5 minutes for the ferry; (2) less than 10 minutes for the ferry? f. Suppose John leaves at 8:10 A.M. What is the probability John will wait (1) less than 5 minutes for the ferry; (2) less than 10 minutes for the ferry? g. What appears to be the best time for John to leave home if he wishes to maximize the probability of waiting less than 10 minutes for the ferry?
