Question

If A = {1, 2} and B = {2, 3, 4}. How many relations are possible? Find all relations also.

Answer 1

Answer:

=22×2=24=16

Step-by-step explanation:

Given, A = {1,2} and B = {3,4}.

Number of elements in set A = n(A)=2

Number of elements in set B = n(B)=2

Number of relations from A to B = 2n(A)×n(B)

=22×2=24=16
