In Lecture 24, we talked about the expectation of a 2D random variable, and more generally the expectation of any function of a 2D random variable. In particular, we looked at the covariance of two variables. We finished the lecture by giving the definition of conditional probability density function and illustrating it with an example.

Action items for students (to be completed before next lecture)
