Deborah Hollwager, a concessionaire for the Amway Center in Orlando, has developed a table of conditional values for the various alternatives (stocking decisions) and states of nature (size of crowd):

                            

If the probabilities associated with the states of nature are 0.3 for a large crowd, 0.5 for an average crowd, and 0.2 for a small crowd, determine:
a) The alternative that provides the greatest expected monetary value (EMV).
b) The expected value of perfect information (EVPI).
