The minimax regret strategy is: d. If the P(s)=0.2, P(s2)=0 5 and p(sx)=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, are (/(s)= 0.1, A(: | s2)= 0.05, P( | s3)= 0.2, compute the revised or posterior probabilities Ps 10. p(521) and Ps3 ]). e.
