  • Formal Definition of Random Variable

    Let (Ω, ℱ, P) be a probability space, and (E, ℰ) a measurable space. Then an (E, ℰ)-valued random variable is a function X: Ω→E, which is (ℱ, ℰ)-measurable. That is, such function that for every subset B ∈ ℰ, its preimage lies in ℱ: X −1(B) ∈ ℱ, where X −1(B) = {ω: X(ω) ∈ B}. (Wikipedia: Random Variable: Formal Definition) Thought I’d share one the few things that brought a…
