Suppose that you own restaurant and the following two possible outcomes are possible for any week day: low demand and high demand. If you've the high demand, your profits would be $2,000; if you've the low demand, you'd lose $500 (- $500). If the probability of a high demand is 20% (or 0.20) and the probability of a low demand is 80% (0.80), what are your expected profits for any given day?
