Discrete probability distributions (Discrete random variables)

A worksheet covering the subtopic on discrete probability distributions for the first year of A-level Maths. Includes a general intro, tabulating a probability distribution and other forms in which it might be defined, cumulative distribution function, expected value of a distribution. You’ll have to look elsewhere for tricky questions but this covers the need-to-knows.

Answers are on page 3 but I’ve also included a set of detailed solutions.
