Answer :
a subset of A×B
Solution :
A relation between A and B is a subset of A×B .
Explanation :
• Cartesian Product : If A and B are any non-empty sets then the set of all ordered pairs (a , b) such that a € A and b € B is called the cartesian product of the set A with set B and it is denoted by A×B .
→ A×B = { (a , b) : a € A and b € B } .
• Relation : if A and B are two sets then a relation R from A to B is a subset of A×B .
→ R ⊆ A×B
