A primer on Probability

Monty Hall and Interpretations of Probability : EvolutionBlog: “If I say that X has probability p, what does that mean? What sort of thing is X, and what does the number p represent?

Philosophers have spilled a lot of ink on this question, with no clear answer emerging. Instead there are a handful of major schools of thought on the issue. Each school captures an important aspect of what we mean when we talk about probability, but none seems to provide a comprehensive account.

One possibility is the so-called classical interpretation. It is classical because it shows up in the earliest formal treatments of probability, for example in the work of Pascal. Laplace was probably the most famous adherent of this view.”
