2. A continuous improvement has helped a company to raise savings with associated probabilities shown in the table below. The useful life is 5 years with a probability of 0.6 and 3 years with probability of 0.4. Annual Benefit $15.000 Probability 0.25 0.45 0.3 $25,000 2.1. Determine the joint probability distribution for savings per year and useful life. 2.2. Determine the expected NPW if an investment of $50,000 is required. No salvage is expected. Use a MARR of 10%
