Answer 1

Answer:

Step-by-step explanation:

The number of relations that can be defined from A and B is: ... Relations and Functions ... Let A and B be finite sets containing m and n elements respectively. ... Since every subset of A×B is a relation from A to B, therefore, number of relations from A to B is equal to the number of ... Let A={x,y,z} and B={1,2}
