Mark the correct alternative in each of the following:

If the set A contains 5 elements and the set B contains 6 elements, then the number of one-one and onto mappings from A to B is


Given that set A contains 5 elements and set B contains 6 elements.


Number of one-one and onto mappings from A to B means bijections from A to B.


Number of bijections are possible only when n(B) < n(A).


But here, n(A) < n(B)


So, the number of one-one and onto mappings from A to B is 0.
