Question

Let A={a,b,c} and let B={1,2,3,4,5}. Determine ​n(AxB​).

A) 12
B) 15
C) 9
D) 20

Answer 1

The number of elements in the Cartesian product of sets A and B is 15.

Step-by-step explanation:

The notation AxB represents the Cartesian product of sets A and B. In this case, A={a,b,c} and B={1,2,3,4,5}. To determine the number of elements in AxB, we multiply the number of elements in set A by the number of elements in set B. The number of elements in the Cartesian product AxB is found by multiplying the number of elements in set A and set B. Since A has 3 elements and B has 5 elements, the number of elements in AxB is 3*5 = 15.
