Three entrepreneurs consider establishing a startup company to develop an application to facilitate car sharing in their hometown. They might rent a small office in the town, adopt a home office system or abandon the project. Moving to an office will bring more professional customers but rents are high in the town. Taking the decision depends on the expectations regarding the market size. They have recently performed a brainstorming session to estimate their revenues and expenses. $100,000 net income is expected if the market is favorable, but $60,000 will be lost if it is not. Working at home brings $50,000 profit in a favorable market and a $10,000 loss in an unfavorable market. Experts predict that the market will be favorable with a chance of 60%. To minimize the risk of losing money, the entrepreneurs also consider the option of buying a marketing research study and decide based on the results. The study costs $10,000. The results are reliable; there is a 0.95 probability that a positive result will be output if the market conditions are favorable. If the marketing environment is unfavorable, there is only a probability of 0.10 of getting positive results from the research.
