$If set A has 3 elements and set B has 2 elements, then the number of elements in the Cartesian product A \times B is$

A. $5$
B. $6$
C. $8$
D. $9$

Show correct answer & step-by-step solution

Correct answer: B — $6$

Solution

The number of elements in the Cartesian product of two finite sets A and B is given by n (A \times B) = n (A) \times n (B) . Thus, 3 \times 2 = 6 .
