describe Decision making using EMV and EVPI.
A concessionaire for the local ballpark has established a table of conditional values for the various alternatives (stocking decision) and states of nature (size of crowed).

If the probabilities related with the states of nature are 0.30 for a large crowed? 0.50 for an average crowed and 0.20 for a small crowed, determine (a) the substitute that provides the greatest expected monetary value (EMV) (b) the expected value of perfect information (EVPI).
