For the three sets namely the set A of all odd numbers less than 10, the set B of all states of South India and the set C of all even natural numbers less than or equal to 10, list out all their elements.
The list of elements of A are 1, 3, 5, 7, 9.
The list of elements of B are Karnatka, Andra Pradesh, Tamilnadu and Kerala.
The list of elements of C are 2, 4, 6, 8, 10.
We use thefollwing notation to represent this A = {1, 3, 5, 7, 9}; B = {Karnatka, Andra Pradesh, Tamilnadu and Kerala} and C = {2, 4, 6, 8, 10}. This method of representing a set by writing all its elements is called Roster method or Tabular method. So, Roster method or Tabular method is a method in which we write all the elements inside a pair of brackets {}.
