Question

how many relations are possible on set A if A has 4 elements?​

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. If A has 4 elements and B has 8 elements, then what are the minimum and maximum number of elements in A ∩ B respectively?
