Elements of a Set
A set can be defined as a group or a collection of well-defined objects, numbers or alphabets e.g. collection of books, shoes, cooking utensils, alphabets, clothes. A set is denoted by capital letters such as A, B, C, etc. while small letters are used to denote the elements e.g a, b, c, etc.

Elements of a Set: These are the elements or members of a given set. The elements are separated by commas and enclosed by a curly bracket {}.

e.g P = {1,2,3,4,5}, 3 is an element of P.

Example: List the elements in each of the following sets

P = {Even numbers from 1 to 10}

B = {Odd numbers from 10 to 20}

Solution

P = {2, 4, 6, 8, 20}

B = {11, 13, 15, 17, 19}
