Cardinality of a Set

The total numbers of unique elements in the set is called the cardinality of the set . The cardinality of the countably infinite set is countably infinite e.g.

Introduction to Sets in Discrete Structure

Introduction

Set is defined as a collection of distinct objects of same type or class of objects.

THe objects of a set are called elements or members of the set . Objects can be numbers , alphabets , Names etc.

e.g : - A{1.2.3.4.5}
