a company is considering a project that has a 70% probability of producing $5,000 in annual benefits and a 30% probability of producing 10,000 annual benefits. For each probability there is 75% chance that the project life will be only 5 years but a 25% chance that the project life will be 10 years. If the initial investment for the project is $30,000 and the firm's MARR is 12% determine the expected present worth of the project and B the probability that the present worth would be negative.
