This lecture elaborates on joint, conditional, and marginal distributions, introducing the 2-D LOTUS. It establishes the condition E(XY)=E(X)E(Y) for independent variables and solves the expected distance and chicken-egg problems.
We discuss joint, conditional, and marginal distributions (continuing from Lecture 18), the 2-D LOTUS, the fact that E(XY)=E(X)E(Y) if X and Y are independent, the expected distance between 2 random points, and the chicken-egg problem.
