Prove that a composition of two measurable maps is measurable. 7. Random variables induce probability measures on R Let X be a random variable on a probability space (Ω , F , P ). Prove that X induces a probability measure on R in the following sense. For every Borel subset A of R , de±ne P ( A ) := P ( X ∈ A ) = P ( ω ∈ Ω : X ( ω ) ∈ A ) . Prove that ( R , R ,P ) is a probability space....
