17. Independence of Random Variables

The chapter presents the concept of independence of random variables, which is crucial in probability and statistics, particularly for modeling uncertainty in various systems. It discusses types of random variables, joint distributions, and conditions for independence for both discrete and continuous variables. Key applications of independence in Partial Differential Equations (PDEs) and statistical modeling are also illustrated.
