Question

Determine the value of n (A×B) if A={a,b} and B={ 1,2,3}.​

Answer 1

Answer: 6

Step-by-step explanation:

(a,1 ) , (a,2 ), (a,3)

(b,1 ) , (b,2 ), (b,3)

the cartesian product = 6

Answer 2

Answer:

Your answer is 6

Step-by-step explanation:

In n(A) there is 2 elements

In n(B) there is 3 elements

so,

   n(A x B) = n(A) x n(B)

                 = 2 x 3

                 = 6

lets check

A x B = {(a,1)(a,2)(a,3)(b,1)(b,2)(b,3)}

here we have 6 elements so this answer is correct
