Mr. Manning is looking to invest in a one-year stock option and has four possible options. The four options have various rates of return based on whether or not the market rises or fall within the coming year. After consulting with his financial planner, he has the following estimates based on the various market outcomes:

Stock Market Rising Market Stable Market Falling
SUA $68,082 $47,373 $36,362
YSP $64,850 $49,320 $44,865
HTC $57,198 $52,949 $50,605
YHA $59,766 $59,766 $59,766

Mr. Manning’s planner has estimated that the probability the market rises is 60%, stays stable is 30%, and falls is 10%. To assist Mr. Manning in his decision, build a decision tree to model the decision and answer the following question. You do not need to upload your decision tree for this question.
