Web10 dec. 2024 · (1) Total number of relations : Let A and B be two non-empty finite sets consisting of m and n elements respectively. Then A × B consists of mn ordered pairs. So, total number of subset of A × B is 2 mn. Since each subset of A × B defines relation from A to B, so total number of relations from A to B is 2 mn.
