There are 4 elements in the set A and 8 elements in set B that is n(A) = 4 and n(B) = 8
<h3>Cardinality of a set</h3>
This is the total number of elements in a set. Given the following sets;
A = {c, d, e, f}
B = {odd numbers greater than 5 and less than 23}
B = {7,9,11,13, 15, 17, 19, 21}
Since there are 4 elements in the set A and 8 elements in set B hence n(A) = 4 and n(B) = 8
