Set Theory Basic Concepts and Definitions More broadly, the concept of set membership, which lies at the heart of set theory, explains how statements with nouns and predicates are formulated in our language or any abstract language like mathematics. and some higherlevel concepts in set theory.Theory is belonging: for any given object, either it is a member or it is not. There is no concept of frequency. For example, the set in (9a) is equivalent to the set in (9b). basic concepts of set theory pdf

Basic Concepts of Set Theory: Symbols& Terminology A set is a collection of objects. A wellde ned set has no ambiguity as to what objects are in the set or not. For example: The collection of all red cars The collection of positive numbers The collection of people born before 1980 In this chapter we consider discrete, mainly finite, sample spaces An event is any subset of a sample set (including the empty set, and the whole set) Two events that have no outcome in common are called mutually exclusive events. In discussing discrete sample spaces, it is useful to use Venn diagrams and basic set theory. basic concepts of set theory pdf Hardegree, Set Theory, Chapter 1: Basic Concepts page 4 of 39 39 In pure set theory, every element of every set is itself a set, so no simpleminded syntactic convention can possibly do justice to the richness of possible relations among sets.

The set of all subsets of a set A is called the power set of A and denoted as (A) or sometimes as 2 A. For example, if A a, b, ( A ), a, b, a, b. basic concepts of set theory pdf gures in the development of set theory, Georg Cantor ( ) and Richard Dedekind (1831 1916).
