Existence of a measure-preserving mapping between two given measure spaces? It only takes a minute to sign up. The second method to calculate the total variation distance uses the following result: $$TV(\mu,\nu)=\sup_{ A\in \mathcal{F}}\left|\mu(A)-\nu(A)\right|=\frac{1}{2}\sum_{i=1}^n\left| \mu(i) -\nu(i)\right|.$$. This answers the first part of your question; how to calculate the total variation distance on this set. We'll see in a brief moment why the supremum is achieved on a set and the set's complement always for total variation distance. There are at least 2 ways to compute the total variation distance.
