The video tutorial explains the concept of independent random variables X and Y, and how their expected value is calculated. It covers the definition of expected value, handling of discrete and continuous variables, and the joint distribution of independent variables. The tutorial concludes with the calculation of probability and expectation, emphasizing that the expectation of the product of independent variables equals the product of their expectations.
