Question

If R is a relation on a finite set having n elements, then the number of relations on a is —. ​

Answer 1

Step-by-step explanation:

Now, any subset of AXA will be a relation, as we know that with n elements, 2^n subsets are possible, So in this case, there are 2^4=16 total possible relations.

Answer 2

Answer:

If R is a relation from a finite set A having m elements to a finite set having n elements, then the number of relations from A to B is

${2}^{mn}$
