The corresponding distribution is called Beta dis-tribution with parameters and and it is denoted as B( ; ): Let us compute the kth moment of Beta distribution.

Lecture Notes #21 October 30, 2020 The Beta Distribution Based on a chapter by Chris Piech Pre-recorded lecture: Sections 1 and 3.1 In-lecture: Sections 2, 3.2, 4.1 Not covered: Section 4.2 In this chapter we are going to have a very meta discussion about how we represent probabilities. Lecture take place Mondays 11-12 and Wednesdays 9-10.
