A cost payoff table is given as Cost Payoff Table State of Nature Decision s1 s2 di 358 757 d2 951 444 d3 332 377 s3 809 1035 763 a. The optimistic strategy is: b. The pessimistic strategy is: c. The minimax regret strategy is: d. If the P(si)=0.2, P(S2)=0.5, and P(S3)=0.3, respectively, then the expected payoff strategy is: A e. The expected value of perfect information is: . f. If the conditional probabilities obtained from sample information / are P(I | S1)= 0.1, P(|s2)= 0.05, P1 | $3)= 0.2, compute the revised or posterior probabilities P(s | ), P(sz and plse 1
