In the project described in Problem 18, assume that the net cash inflows are probabilistic variables. Further assume that each forecast net cash inflow is normally distributed with standard deviations of $1,000,

$1,500, $2,000, and $3,500, respectively. Given a required rate of return of 0.2, find the mean forecast LO8 NPV using Crystal Ball. What is the probability that the actual NPV will be positive?
