The Laplace criterion involves assigning equal probability weights to each possible outcome. In this case, the possible outcomes are hiring one, two, or three examiners. By summing the scores for each outcome and dividing by the number of outcomes, we get the expected value. Hiring one examiner has an expected score of (0.7 x 90) + (0.3 x 60) = 81, hiring two has an expected score of (0.7 x 180) + (0.3 x 150) = 169.5, and hiring three has an expected score of (0.7 x 270) + (0.3 x 240) = 256.5. Therefore, the Laplace criterion suggests hiring three new examiners for the best outcome.
