The number of distinct elements or members in a finite set is known as the cardinal number of a set. Basically, through cardinality, we define the size of a set. The cardinal number of a set A is denoted as n(A), where A is any set and n(A) is the number of members in set A.
Consider a set A consisting of the prime numbers less than 10.
Set A ={2, 3, 5, 7}.
As the set A consists of 4 elements, therefore, the cardinal number of set A is given as n(A) = 4.
