Si ='weak demand for both Chardonnay and Riesling S2 = 'weak demand for Chardonnay, strong demand for Riesling S3 = strong demand for Chardonnay, weak demand for Riesling Sn = strong demand for both Chardonnay and Riesling P(s) = 0.25 Pls) = 0.28 P/s3) = 0.27 P(sa) = 0.20 Revenue projections show an annual contribution to profit $ 16,000 if the partners only plant Chardonnay grapes and demand is weak for Chardonnay wine, and $ 71,000 if they only plant Chardonnay grapes and demand is strong for Chardonnay wine. Revenue projections show an annual contribution to profit $ 26,000 if the partners only plant Riesling grapes and demand is weak for Riesling wine, $ 44,000 if they only plant Riesling grapes and demand is strong for Riesling wine. If the partners plant BOTH types of grapes, tha annual profit projections are shown in the following table. Chardonnay Demand Weak Strong Riesling Demand Weak Strong 21,000 42,000 25,000 62,000 a. Develop a decision tree to represent the decision to be made by the three partners. b. Use the expected value approach to recommend which alternative the three partners should follow in order to maximize expected annual profit.
