Consider the following after-tax cash flows for an 8-year project life following a two-year investment period. The investment flows (F_0 and F_1) are independent of the operating cash flows (F_2 through F_9). The firm's MARR is 15%. If the annual operating cash flows are mutually independent, determine the mean and variance of the PV of the project. If the annual operating cash flows are perfectly correlated (positively) with one another, determine the mean and variance of the project. In part a or part b, is it meaningful to compute the mean and variance of IRR of this project? In part b, assume that all the project cash flows (including the investment flows) are normally distributed with the means and variances specified. What is the probability that the PV of the project will exceed $200? Suppose that the operating cash flows are negatively correlated with one another. Assume a perfect correlation coefficient of - 1. Compute the variance of the project. What can you conclude from the variance calculation
