Types of Sets
Finite and Infinite Sets
Finite Sets
A set which contains a definite number of elements is called a finite set.
Example − S = { x | x ∈ N and 70 > x > 50 }
Infinite Sets
A set which contains infinite number of elements is called an infinite set.
Example − S = { x | x ∈ N and x > 10 }

Disjoint Sets
Empty Sets
An empty set contains no elements. It is denoted by ∅. As the number of elements in an empty set is finite, empty set is a finite set. The cardinality of empty set or null set is zero.
Example − S = { x | x ∈ N and 7 < x < 8 } = ∅
