A cost payoff table is given as Cost Payoff Table s3 State of Nature Decision s1 s2 di 421 852 d2 1172 336 d3 275 737 567 1125 1035 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 d. If the P(sy)=0.2, P(sz)=0.5, and P(sz)=0.3, respectively, then the expected payoff strategy is: e. The expected value of perfect information is: f. If the conditional probabilities obtained from sample information I are pli | s)= 0.1, P(1|s2)= 0.05, P(1|s3)= 0.2, compute the revised or posterior probabilities P(s, |). P(s2 | ) and P(s3 | 1).
