2. In Problem 3 of Chapter 13 (Burger Office Equipment), suppose that the amount of labor required per desk is uncertain. Assume that the amount of labor required for a standard desk is triangular with parameters (9, 10, 12), and the amount of labor required for a deluxe desk is triangular with parameters (14, 16, 21). If the company wishes to limit the probability of requiring overtime beyond the 400 hours available to at most 20%, how many desks of each type should they produce?
