Question

Let sets A and B be defined as follows.

Answer 1

There are 4 elements in the set A and 8 elements in set B that is n(A) = 4 and n(B) = 8

Cardinality of a set

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
