ROSTER METHOD OR TABULAR METHOD

Roster Method or Tabular Method 

In the Roster method, the members of a Set are listed inside the braces { } (Second Braces) and separated from each other by commas. If an object appears, more than one time in a Set then we will write it once only.

Example- 

1) If the Set ‘B’ of the first six even natural numbers are written as { 2, 4, 6, 8, 10, 12 }

2) The Set ‘D’ of the letter of the word BANANA is written as  D = { B, A, N, A }

The Set ‘X’ of the letter of the word CALCUTTA is written as  X = { C, A, L, U, T }
