In designing a new space vehicle, NASA needs to decide whether to provide 0, 1 or 2 backup systems for a critical component of the vehicle. The first backup system, if included, comes into use only if the original system fails. The second backup system, if included, comes into use only if the original system and the first backup system both fail. NASA engineers claim that each system, independent of the others, has a 1.5% chance of failing if called into use. Each backup system costs $70,000 to produce and install within the vehicle. Once the vehicle is in flight, the mission will be scrubbed (ended early) only if the original system and all backups fail. The cost of a scrubbed mission, in addition to production costs, is assessed to be $5,000,000. How many backup systems are needed to minimize NASA’s expected total cost?

A producer of pocket calculators estimates that the calculators fail at a rate of oneevery five years. The calculators are sold for $25 each with a one-year freereplacement warranty but can be purchased from an unregistered mail-ordersource for $18.50 without the warranty. Is it worth purchasing the calculator withthe warranty? For Problem 37, what length of period of the warranty equates the replacementcosts of the calculator with and without the warranty?

A company has prepared a design for a new product which it can either sale for K100 000 or develop into a marketable product at a cost of K150 000. The chances of success if the product is developed are 0.7. If this attempt fails the design can only be sold at K20 000. If the attempt succeeds the business has the choice of either selling the design and developed product for K180 000 or marketing the product. If the product is marketed then there is a 0.6 probability that the product will generate a cash inflow of K800 000 and a 0.4 probability that it will generate a cash outflow of (K100 000). Both figures exclude items previously mentioned Supposing there is a small change in the estimated probabilities of success and failure in the product development phase from 0.7: 0.3 to 0.6: 0.4 what would be the change in expected value?
