Hello need help with A-E

Lemon, a scooter rental company, is currently evaluating two mutually exclusive investments. After doing a scenario analysis and applying probabilities to each scenario, it has determined that the investments have the following distributions around the expected NPVs. Several members of the management texm have suggested that Project A should be selected because it has a higher pocential NPV: Other members have suggested that Project B appears to be more conservatwe and should be selected. They have asked you to resolve this question. a. Calculate the expected NPV for both profects. Can the question be resolved with this information alone? b. Calculate the variance and standard deviation of the NPVs for both projects. Which project appears to be riskier? c. Calculate the coefficient of variation for both projects. Does this change your opinion from part b? d. Calculate the probability of a negarive NPV for both projects. e. Which project should be accepted Why
