THE ROLE OF PROBABILITY THEORY IN EVERYDAY LIFE

Abstract

This thesis highlights the role and practical importance of probability theory in everyday life. It also analyses how this theory helps people make rational decisions in uncertain situations and emphasises its significance in modern society. Probability theory is not only one of the fundamental branches of mathematics but also an effective tool for decision-making under conditions of uncertainty. Today, it is widely applied in weather forecasting, medical diagnosis of various diseases, the organisation of insurance systems, the assessment of economic risks, and the analysis of statistical data. The thesis discusses several areas in which probability theory is used in daily life and presents illustrative examples of its applications. The findings demonstrate that probability theory is important not only from a theoretical perspective but also as a practical instrument in solving real-world problems.
