A decision maker is working on a problem that requires her to study the uncertainty surrounding the payoff of an investment.
	There are three possible levels of payoff -$1,000, $5,000, and $10,000. As a rough approximation, the decision maker believes that each possible payoff is equally likely.
	But she is not fully comfortable with the assessment that each probability is exactly 1/3, and so would like to conduct a sensitivity analysis.
	In fact, she believes that each probability could range from 0 to 1/2.
A.	Show how a Monte Carlo simulation could facilitate a sensitivity analysis of the probabilities of the payoffs.
B.	Suppose the decision maker is willing to say that each of the three probabilities could be chosen from a uniform distribution between 0 and 1.
	Could you incorporate this information into your simulation? If so, how? If not, explain why not, or what additional information you would need.
