Definition: Given a random experiment, a probability space $(\Omega, \mathcal{E}, P)$ is a triple consisting of

the sample space $\Omega$, i.e. the set of all possible outcomes from this experiment;

an event space $\mathcal{E} \subseteq 2^\Omega$, i.e. a set of subsets from the sample space, called events;

a probability measure $P: \; \mathcal{E} \rightarrow [0,1]$, i.e. a function mapping from the event space to the real numbers, observing the axioms of probability.
