Question

What is the cardinality of
the set A={a,e,i,o,u}
​

Answer 1

n(A) = 5

Explanation:

The cardinality of a set is the total number of elements in the set

Given the set

A = {a,e,i,o,u}

The total number of letters we have in the set is 5 i.e. a, e, i ,o and u. Hence the cardinality of the set A is 5. This can also be written as n(A) = 5
