The tree diagram in the figure below describes the uncertain cash flows for an engineering project. The analysis period is two years and MARR = 8% per year. Based on this information, what are the E(PW), V(PW), and SD(PW) of the project? What is the probability that PW ≤ 0? Click the icon to view the tree diagram.
