Sets can be REPRESENTED in two ways −

Roster or Tabular FORM: The set is represented by listing all the elements comprising it. The elements are enclosed within braces and separated by commas.

Example 1 − Set of vowels in English alphabet, A={a,e,i,o,u}A={a,e,i,o,u}

Example 2 − Set of odd numbers LESS than 10, B={1,3,5,7,9}

Set BUILDER Notation: The set is defined by specifying a property that elements of the set have in COMMON. The set is described as A={x:p(x)}A={x:p(x)}

Example 1 − The set {a,e,i,o,u}{a,e,i,o,u} is written as- A={x:x is a vowel in English alphabet}A={x:x is a vowel in English alphabet}

Example 2 − The set {1,3,5,7,9}{1,3,5,7,9} is written as -B={x:1≤x<10 and (x%2)≠0}
