Please solve a and b. Thank you!

Expected value analysis: San Lucas Corporation San Lucas Corporation is considering investment in robotic machinery based upon the following estimates: Cost of robotic machinery $4,000,000 Residual value 300,000 Useful life 10 years Assume San Lucas Corporation assigns the following probabilities to the estimated annual net cash flows: Annual Net Probability Cash Flow of Occurring 5900,000 0.10 700,000 0.50 500,000 0.40 Total 1.00 a. Compute the expected value of the annual net cash flows. Expected Value Annual Net Cash Flow $900,000 700,000 500,000 Total b. Determine the expected net present value of the equipment, assuming a desired rate of return of 10% and the expected annual net cash flows computed in part (a). Use the present value tables (Exhibit 2 and 5) provided in the chapter in determining your answer. Net present value $
