The company estimates that it has a 60% chance of winning the contract with this bid. If the firm wins the contract, it can choose one of three methods for getting the oil from the shale. It can develop a new method for oil extraction, use an existing (inefficient) process, or subcontract the processing to a number of smaller companies once the shale has been excavated. The results from these alternatives are as follows:Develop new process:OutcomesProbabilityProfit (1,000,000s)Great success.30$ 600Moderate success.60300Failure.10-100Use present process:OutcomesProbabilityProfit (1,000,000s)Great success.50$ 300Moderate success.30200Failure.20-40Subcontract:OutcomeProbabilityProfit (1,000,000s)Moderate success1.00250The cost of preparing the contract proposal is 2 million.
