And there are two ways to write sets

- roaster form

- set builder form

Answer 2

Answer:

there are many types of sets -:

1. empty set -: The set in which has no element is called empty set .

-: It is also called as null set

-: It is denoted as { } .

ex -: A set of all odd integers divisible by 2 .

2. Singleton set -: The set which has only one element is called Singleton set .

ex-: A set of a whole no. but not a rational no. .

3. finite set -: The set which has finite no. of elements is called finite set .

ex-: A set of all even integers less than 10 .

4. Infinite set -: the set which has infinite no. of elements is called infinite set .

ex.-: the set of all the integers .

5. Equal sets -: Two sets having same elements & same no. of elements are 2 equal sets .

ex.-: A = { 1 , 2 , 3 } & B = { 1 , 2 , 3 }

6. equivalent sets -: two sets having same no. of elements are 2 equivalent sets .

ex.-: A = { a, b , c} & B = { 1 , 2 , 3 }

7. power set -: the set of all the subsets of a set is called power set .

8. Universal set -: A universal set is a set which contains all the elements of related sets .

ex.-: the universal set of A = { 1 , 2 , 3 } & B = { 3 , 4 , 5 } is U = { 1 , 2 , 3 , 4 , 5 } .
