Problem 4 Uncertainty in future events Project investment (first cost) =$4 million dollars. Interest rate per year: 12% Assume that the probability distributions for annual benefit and life are unrelated or statistically independent. a) Calculate the probability distribution for the PW. b) Use the expected values for annual benefits and life to estimate the present worth. c) Use the probability distribution function of PW in (a) to calculate the expected value EV(PW) Is this project attractive
