In mathematics, a probability space is a set S, together with a σ-algebra X on S and a measure P on that σ-algebra such that P(S) = 1.
The set S is called the sample space and the elements of X are called the events.
The measure P is called the probability measure, and P(E) is the probability of the event E.
The above is a compact form of stating the probability axioms.
Note that not all subsets of a probability space are events.
