If basic probability becomes a problem:.
A good description is the first four chapters of
John Rice's Mathematical Statistics and Data Analysis (2nd ed., Duxbury
Press). This is the textbook in Stat 24400, and can be found at the
An even more basic book, extremely well written, is
Statistics by D. Freedman, R. Pisani, and R. Purves (3rd ed,

So long as we are in the finite state space setting: proofs for conditional
expectations and Radon-Nikodym derivatives should be done by
reformulating the problem in terms of conditioning on sets in
