Using a simulation technique calculate Pr(NPV> $250,000) and Pr(NPV<= $0) for the following problem. Assume all the cash flow follows normal distribution. (7 points) Initial investment (CF0): negative $300,000 (certain cash flow) CF1? expected number $200,000, standard deviation $100,000 CF2? expected number $200,000, standard deviation $110,000 CF3? expected number $200,000, standard deviation $121,000
