Assume that we can estimate a project€™s cash flows as follows:

In this case, each annual flow can be represented by a random variable with known mean and variance. Further assume complete independence among the cash flows.
(a) Find the expected NPW and the variance of this project at i = 10%.
(b) If all cash flows are normally distributed with the given means and variances, what is the probability that the NPW will exceed $200?
