The article reflects the author's methodological position that the phenomena of uncertainty and risk are considered within the context of decision-making problems.

Risk is the result of a decision and is always associated with a person who not only makes a choice, but also estimates the probabilities

... possible outcomes and related losses. Risk is an integral indicator that combines estimates of both the probability of a decision and of the quantitative characteristics of its consequences. Every person has her own system of preferences, therefore there is no universal functional integrating estimates of probabilities and consequences. As a result, a person chooses the alternative that most closely matches her goals, assessments and value system. The typology of uncertainties in decision-making tasks, previously developed by the author, is supplemented.
