Question

If A={1, 2, 3} and B=(x, y} then total number of relation from A to B is​

Answer 1

Answer:

It is given that A={x,y,z} and B={1,2}

∴ A×B={(x,1),(x,2),(y,1),(y,2),(z,1),(z,2)}

Since n(A×B)=6

The number of subsets of A×B is 2

6

.

Answer 2

Answer:

64

Step-by-step explanation:

n(a)=3

n(b)=2

no .of relations from A to B =2^pq

= 2 ³×²

= 2⁶

= 2×2×2×2×2×2

= 64
