Question

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 A. m*m B. n*m C. 2 mn − 1 D. 2 mn

Answer 1

Answer:

c) $2^{mn}-1$

Step-by-step explanation:

We have, n(A) = m and n(B) = n

n(A xB) = n(A). n(B) = mn

Total number of relation from A to B = Number of subsets of AxB = $2^{mn}$

So, total number of non-empty relations = $2^{mn}-1$
