Question

If A = { 1 , 2 , 3 } and n( B ) = 2 then the number of relations from A to B is​

Answer 1

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 = 2mn

So, total number of non-empty relations = 2mn – 1

Answer 2

This answer is correct....
