Problem:
In the following profit payoff table for a decision problem with two states of nature and three decision alternatives, the probabilities for s1 and s2 are: p(s1)=0.8 and p (s2)= 0.2
S=State of Nature
D=Decision alternatives
S1 S2
d1 15 10
d2 10 12
d3 8 20
a. What is the optimal decision?
b. Find the EVPI (expected value of perfect information)
