One of Philip Mahn’s investments is going to mature, and he wants to determine how to invest the proceeds of $30,000. Philip is considering two new investments: a stock mutual fund and a one-year certificate of deposit (CD). The CD is guaranteed to pay an 8% return. Philip estimates the return on the stock mutual fund as 16%, 9%, or -2%, depending on whether market conditions are good, average, or poor, respectively. Philip estimates the probability of a good, average, and poor market to be 0.1, 0.85, and 0.05, respectively.
