Question:

Consider the contractor in Example 1.5.4 on page 19. He wishes to compute the probability that the total utility demand is high, meaning that the sum of water and electrical demand (in the units of Example 1.4.5) is at least 215. Draw a picture of this event on a graph like Fig. 1.5 or Fig. 1.9 and find its probability.
