In lecture, I indicated that the remaining sections of Lecture 18 would be taught through posted recordings, as a substitute for our lack of a lecture during Retake A. Well, here they are! Please watch them before the lecture following Retake A.
First is Lec18SecC, where we introduce the Beta distribution, as our final task for topic B3.
Next is Lec18SecD, where we introduce joint mass functions, as our first task in topic B4.
Last is Lec18Ex2, where we construct and apply a joint mass function.
