If a set A has n elements and another set B has m elements, what is the number of relations from A to B ?

Let |A|=n and |B|=m .How many functions can be there from A to B.

A and B arenon-empty sets such that absA = m, absB = n. How many relations can be defined from A to B ? ( Remember that the number of relations is the number of subsets of A xx B ) .

Let Х and У be the sets containing m and n elements respectively. How many one-one functions аre there from Х to У.

Sets A and B have respectively m and n elements. The total number of relations from set A to set B is 64. If m lt n and m ne 1 , write the values of m and n, respectively.

Set A and B have respectively m and n elements. The total number of relations from A to B is 128. If m ne 1, write the values of m and n, respectively.

Sets A and B have respectively m and n elements. The total number of relations from A to B is 64. If mltn and mne1 write the values of m and n respectively.

Sets A and B have respectively m and n elements. The total number of relations from A to B is 64. If mltn and mne1 write the values of m and n respectively.

Sets A and B have respectively m and n elements. The total number of relations from A to B is 64. If mltn and mne1 , write the values of m and n respectively.

How many of the functions Suppose A is a set of n elements and B is a set with m elements are one - one with (i)m=n ,(ii) m n
