The standard **probability axioms** are the foundations of probability theory introduced by Russian mathematician Andrey Kolmogorov in 1933.^{[1]} These axioms remain central and have direct contributions to mathematics, the physical sciences, and real-world probability cases.^{[2]}

There are several other (equivalent) approaches to formalising probability. Bayesians will often motivate the Kolmogorov axioms by invoking Cox's theorem or the Dutch book arguments instead.^{[3]}^{[4]}
