a$.$Which project is least$$ risky, based on the range of possible$$ outcomes?

b$.$Which project has the lowest standard deviation$?$ Explain why standard deviation may not be an entirely appropriate measure of risk for purposes of this comparison.

c$.$Calculate the coefficient of variation for each project. Which project do you think$$ Greengage's owners should$$ choose?
