A firm is considering two alternative projects. Project A needs an investment of $800,000. Project B needs an investment of $750,000. Relevant annual cash flow data for the two projects over their expected seven-year lives are as follows:

Project A Project B

Pr. Cash Flow Pr. Cash Flow

0.50 $ 0 0.045 $ 0

0.50 500,000 0.910 200,000

0.045 400,000

Calculate the expected value, standard deviation, and coefficient of variation of cash flows for each project.
