• A. A measure of risk associated with a choice
• B. A measure of satisfaction or value derived from an outcome
• C. A statistical method for summarizing data
• D. A formula used to calculate expected values

Answer: (B)

The term 'utility' in decision theory signifies a measure of satisfaction or value derived from an outcome. Utility is a fundamental concept that captures an individual's preferences and the level of happiness or satisfaction they derive from different choices or outcomes. In this context, individuals use the concept of utility to evaluate and compare the desirability of different prospects, allowing them to make informed decisions under uncertainty. The utility function assigns a numerical value to every possible outcome, reflecting the subjective preferences of the decision-maker. Higher utility values indicate more preferable outcomes. This concept is essential for understanding how people assess risks, rewards, and trade-offs when making decisions. In decision-making processes involving uncertainty, such as in the realm of finance, economics, or insurance, the idea of utility helps to model and analyze choices that consider both risk and the potential satisfaction gained from various outcomes.
