Question

Given set A = {a,b} and set B = {1,2}. How many relations are possible from set A to set B. *​

Answer 1

Answer:

If n (A) = p

n (B) = q

$n(a) \times n(b) \: = 2 {?}^{pq?}$

Step-by-step explanation:

A×B = 2^2×2

= 2^4

= 16

Answer 2

2^4=16

Step-by-step explanation:

Set A={a,b}

Set B={1,2}

n(A)=p=2

n(B)=q=2

n(A×B)=2^pq

=2^2×2

=2^4

=16

.•. There are 16 relations possible in between set A and setB.
