Basic ideas In this chapter, we don’t really answer the question ‘What is probability?’ No-body has a really good answer to this question. We take a mathematical approach, writing down some basic axioms which probability must satisfy, and making de-ductions from these. We also look at different kinds of sampling, and examine
