Let $\mu$ be an absolutely continuous probability distribution with distribution function F and density f. For any Borel set $\Lambda$ and $a<b$, let v($\Lambda \cap [a,b]) = \int_{a}^{b} \mathbb{I}_{\Lambda}(x)f(x)dx.$ Show that this defines a probability measure v on the Borel sets of $\mathbb{R}$, and that v=$\mu$....
