Let $P = (\Omega, \mathcal{F}, \mathbb{P})$ be a
D1159: Probability space
such that
(i)
$X : \Omega \to [0, \infty]$ is a
D5101: Random unsigned basic number
on $P$
The
expectation
of $X$ on $P$ is the
D1699: Basic number
\begin{equation} \mathbb{E}_{\mathbb{P}} X : = \int_{\Omega} X \, d \mathbb{P} \end{equation}
