    This case problem is related to a property purchase strategy. The president of Oceanview is deciding whether to bid for a property to build and sell condominiums. However, this depends on whether the state can change the zoning of the property to permit construction of condominiums. Here, the decision is whether to bid for the property, and chance events are firstly, whether the bid can be successful, and secondly, whether the state will approve the zoning change. To assess the likelihood that the state will approve the zoning change, the president can hire a market research service. Hence, the president is facing another decision as to whether he wants to hire the market research service. As a result, if he chooses to hire the service, besides the two chance events mentioned above, there is another chance event concerning whether the market research predicts that the zoning change will be approved. The consequence is that the company will have different profits or losses.…

    3.31 Mas Asmyra has done some analysis about the profitability of the bicycle shop. If Mas builds the large bicycle shop, he will earn $60,000 if the market is favorable, but he will lose $40,000 if the market is unfavorable.
