In mathematics, we encounter various structural elements such as definitions, axioms, theorems, lemmas, conjectures, and corollaries, among others. For this section, our specific focus lies on axioms.
An axiom is a statement or proposition that is accepted as true without requiring formal proof within a particular mathematical system. Axioms serve as the foundational principles upon which the rest of a theory or system is built. They provide the starting point for logical reasoning and deduction within that system.
To formalise probability as a branch of mathematics, Russian mathematician Andrey Kolmogorov formulated three axioms of probability in 1933. These axioms serve as essential cornerstones upon which the entire mathematical theory of probability is built.
