Which alternative is most desirable from the cost viewpoint

Reference no: EM13210142

The design of a system is to be pursued from one of the available alternatives. Each alternative has a life cycle cost associated with an expected future. The costs for the corresponding futures are given in the following table (in millions of dollars). If the probabilities of occurrence of the futures are 30%, 50% and 20% respectively which alternative is most desirable from an expected cost viewpoint? Assume interest 10%.
