Difference of sets
Asked by abhinay.bhatta | 19 Nov, 2009, 10:05: PM
Expert Answer
Here, A is a subset of B.
That means all the elements of A are included in B.
Which ⇒ A - B = {}, a null set.
Just by knowing this we cannot comment of B - A.
Since there can be elements in B which are not contained in A at the same time satisfying the above two conditions i.e A C B, and A - B = { }.
Please confirm why did you write -AB. Is the question incomplete.
