Let `n(A)=m and n(B)=n` that the total number of non-empty relations that can be defined from A to B is

Let n(A)=m and n(B)=n Then, the total number of non-empty relations that can be defined from A to B is:

Let n(A) = m and n(B) = n. Then the total number of non-empty relations that can be defined from A to B is

Let n(A) = m and n(B) = n. The total number of non-empty relations that can defined from A to B is

Let n(A) = 6 and n(B) = p . Then , the total number of non - empty relations that can be defined from A to B is

Let n(A) = m and n(B) = n, then the number of non-empty relations from A to B is

Let A={x_(1),x_(2),......X_(m)},B={y_(1),y_(2),...,,y_(n)} then total number of non-empty relations that can bedefined from A to B, is

Let A={x_1,x_2,......X_m},B={y_1,y_2,.....,y_n} then total number of non-empty relations that can bedefined from A to B, is (i) m^(n) (ii) n^(m)-1 (iii) mn-1 (iv) 2^(mn)-1

If n(A)=4 ,then total number of reflexive relations that can be defined on the set A is
