**Set -**Set is an ordered collection of distinct elements . Set is the part of basically Discrete Mathematics but widely used in most of the fields as Set Thory , Permutations and Combinations , Artificial Intelligence , Machine language etc in the form of Sets .

example -

A = { 1 , 2 , 3 , 4 , 5}

B = { 1 , 2 , 2 ,3 ,4}

a = { 1 , 2 , 3 , 4 , 5}

C = { 1 , 2 , A , B , क , ख , ग }

Note -

Here A is a Set because it contains all the distinct elements .Here B is not a Set because it contains duplicate element 2 .a is not a Set because it must be represented by capital letter as A .C is a Set if all the letters of Hindi , english , symbols , Integers are allowed Otherwise not a Set .

**Cardinality of Set -**It shows the number of elements available in that Set .

example - A = { 1,2,3,4,5} Cardinality of A =

**| A |**= 5

**Representation of Sets -**There are several methods to represent a set like -

**1. Tabular / Roaster Method -**This method basically applies on the sets of small number of elements tha…
