Oilco must determine whether or not to drill for oil in the South China Sea. It costs $70,000 to drill for oil. If oil is found, the revenue is estimated to be $400,000. At present, Oilco believes there is a 45% chance that the field contains oil. Before drilling, Oilco can hire (for $25,000) a geologist to obtain more information about the likelihood that the field will contain oil. There is a 80% chance that the geologist will issue a favorable report and a 20% chance of an unfavorable report. Given a favorable report, there is an 60% chance that the field contains oil. Given an unfavorable report, there is a 15% chance that the field contains oil. Determine the optimal strategy, the expected profit, EVSI and EVPI. What is the Expected Value of Perfect Information (EVPI)? (5 pts) Select one: a. EVPI=$38,500 b. EVPI=$55,000 c. EVPI=$54,000 d. EVPI=$48,000
