•EXAMPLES »

For example, consider the single-digit numbers 1 through 9: If {1, 2, 3, 4, 5, 6, 7, 8, 9} is our larger set, then A and B are part of that set. Thus A and B are each a subset of this larger set, called the Universal Set. . All other sets are subsets of the universal set.

Symbol Meaning Example

a ∈ A Element of: a is in A 3 ∈ {1, 2, 3, 4}

b ∉ A Not element of: b is not in A 6 ∉ {1, 2, 3, 4}

∅ Empty set = {} {1, 2} ∩ {3, 4} = Ø

Universal Set: set of all possible values (in the area of interest)

A universal set is a set which contains all the elements or objects of other sets, including its own elements. It is usually denoted by the symbol 'U'. Suppose Set A consists of all even numbers such that, A = {2, 4, 6, 8, 10, …} and set B consists of all odd numbers, such that, B = {1, 3, 5, 7, 9, …}.
