11. Consider the following 3 alternatives: (in $$ millions) A B C Initial cost 50 150 110 Uniform annual benefit 30 45 45 All three alternatives have a useful life of 8 years and the interest rate is 10%.

The optimistic estimate of annual savings is $40,000 and has a probability of 0.25. The pessimistic estimate is $20,000 and has a probability of 0.35. (a) What is the probability of the most likely estimate occurring? (b) What is the expected value for the annual savings? 14.
