1.	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, isA. `m^(n)`B. `n^(m)-1`C. mn-1D. `2^(mn)-1`
Answer» Correct Answer - D We have, `n(A)=m and n (B) =n` `n(AxxB)=n(A)*n(B)` Total number of releation from A to B =`2^(mn)-1=2^(n(AxxB)^(-1))-1`
