When these probabilities are known or can be estimated, the choice of an optimal action, based on these probabilities, is termed as decision making under risk. The quality of the optimal strategy depends upon the quality of the judgments. Certainty, risk and uncertainty are thus going to impact his decision-making process (along with the fact that his boss is breathing down his neck for the right decision). The quantity of risk is equal to the sum of the probabilities of a risky outcome (or various outcomes) multiplied by the anticipated loss as a result of the outcome.

ABSTRACT - The purpose of this paper is to provide an overview of psychological research on decision making under risk, with an emphasis on insurance behavior. We compute the expected payoff, also called the return (R), for each action R(a) = Sums of [X(a,s) p(s)]. DECISION MAKING UNDER RISK: APPLICATIONS TO INSURANCE PURCHASING. The process is as follows: Whenever the decision maker has some knowledge regarding the states of nature, he/she may be able to assign subjective probability estimates for the occurrence of each state. This indicates that the optimal act is again A1. Various uncertainties are quantified in terms of probabilities.

The expected value is the value that the decision maker could obtained for each scenario, multiplied for the probability of occurrence of each scenario: as a matter of fact, the decision maker will be oriented to select the alternative with the higher expected value. There are two main concepts to consider in order to take decisions in risk conditions, which are the expected value and the measure of the risk.
