Decision Making

Making decisions under uncertainty requires structured risk assessment, which is best achieved by calculating expected values and evaluating key assumptions. Relying on pure intuition, as suggested in option A, is incorrect because it ignores objective data and increases the risk of cognitive bias.

Since the two dice rolls are independent events, the total probability is found by multiplying the individual probabilities of 1/6 for each roll, resulting in 1/36. Option A is a common error resulting from adding the probabilities or incorrectly doubling the denominator.

Since the entire set of A is contained within B, and B is entirely contained within C, it logically follows that all of A must be within C. A diagram for this topic isn't available yet — the worked example below walks the same reasoning step by step.

• !Option A is incorrect because C is the largest category, meaning there could be members of C that are not part of A.
• !Option D is incorrect because it includes the area inside circle C.
• !Option A is a common error resulting from adding the probabilities or incorrectly doubling the denominator.
• !Relying on pure intuition, as suggested in option A, is incorrect because it ignores objective data and increases the risk of cognitive bias.
