 Department of Mathematics
 Synopsis:

The subject is devoted to the introduction to Theory of probability on measuretheoretic level for discrete models, continuous distributions and general distributions of random variables. We deal with the examples of distributions including multidimensional Gaussian distribution and their properties. Further the (non)+integral characteristics of random variables (E, Var,...), convergence modes (Lp, P, a.s., D) and variants of limit theorems are derived (LLN, CLT).
 Requirements:

01MAA34 or 01MAAB34.
