Question

let A={x,y,z} and B= {1,2,3} find the number of relation from Ato B​

Answer 1

Step-by-step explanation:

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:

Number of relation from A to B

n(A × B) =9
