as from all the maximums of the decision the minimum is the D2.

as from all the minimum of the decisions, the maximum is the D3.
3. minimax regret approach
in this we will select the max of the column then subtract rest from the max and form a new matrix.

now we will find the maximum of all the rows and choose the minimum of them so in this case the decision will be D3 as 5 is minimum.

The following profit payoff table shows profit for a decision analysis problem with two decision alternatives and three states of nature. Suppose that the decision maker obtained the probability assessments P(S1) = 0.65, P(S2) = 0.20, and P(S3) = 0.15. State of Nature Decision Alternative S1 S2 S3 d1 150 175 50 d2 175 75 100 Use the expected value approach to determine the optimal decision. The optimal decision is?
