First, the expected utility of a lottery is equal to the expectation of the expected utilities of its prizes.
It is better to evaluate a decision by comparing its expected utility to the expected utilities of rival decisions.
Here is the beginning of the table for this gamble if utiles = log: The sum of expected utilities is not infinite: it reaches a limit of about 0.602 utiles (worth $4.00).
Expected utilities that guide decisions are comprehensive.
If acts' expected utilities lack this property, then decision theory may use only expected utilities computed from selected partitions.
Why should we assume that people evaluate lotteries in terms of their expected utilities?
If expected utilities are partition-sensitive, then acts that maximize expected utility may be partition-sensitive.
Then it computes a probability-weighted average of those conditional expected utilities.
Expected utilities obtained from conditional probabilities steer the student's deliberations in the right direction.
To circumvent such impasses, some theorists calculate causally-sensitive expected utilities without probabilities of subjunctive conditionals.
The methodology suggests an optimal design after comparing the expected utilities of the considered design options.
