Step 1: Understanding the Question:
• We judge the Assertion and the Reason about the Maximax criterion and then see whether the Reason explains the Assertion.
Step 2: Detailed Explanation:
• Assertion (A): The Maximax criterion is the criterion of an optimist, who expects the best outcome. It uses no probabilities. So (A) is correct.
• Reason (R): Under Maximax the decision maker finds the maximum payoff for each course of action and then picks the action with the highest of these maximum payoffs. This is how the criterion works, so (R) is correct.
• The procedure in (R) is exactly why the criterion is called optimistic, so (R) explains (A).
Step 3: Final Answer:
The correct option is (A).
