Http://en.wikipedia.org/wiki/Expecte...ity_hypothesis Mình thấy ở đây họ có nói khá rõ là : "Until the mid twentieth century, the standard term for the expected utility was the moral expectation, contrasted with "mathematical expectation" for the expected value."
Và "the expected utility hypothesis is a theory of utility in which "betting preferences" of people with regard to uncertain outcomes (gambles) are represented by a function of the payouts (whether in money or other goods), the probabilities of occurrence, risk aversion, and the different utility of the same payout to people with different assets or personal preferences."
Utility ở đây là sự hài lòng, sự thỏa mãn người dùng.
