Lecture
This lecture covers the estimation of expectation in the context of discrete random variables, focusing on the calculation of the mean value. The instructor explains the concept of expectation, its calculation formula, and its importance in probability theory. Various examples are provided to illustrate the calculation process, including the expectation of a binomial distribution. The lecture emphasizes the significance of expectation in understanding the average outcome of random events and highlights the distinction between theoretical expectation and empirical averages.
