Document Summary

The material in this handout is intended to cover general set theory topics. Information includes (but is not limited to) introductory probabilities, outcome spaces, sample spaces, laws of probabil- ity, and venn diagrams. This covers section 1. 2 and all of chapter 2 from a course in probability by neil weiss. An element is a single item (outcome), typically denoted by . A subset is a set itself, in which every element is contained in a larger set. Suppose the set a is contained in the set b. This is denoted by a b or a b depending on whether or not b has elements which are not in a. If b contains elements that are not in a, then a is called a proper subset of b. A population is the collection of all individuals or items under consideration. An individual could refer to a person, a playing card, or whatever object we are interested in.
