If A and B are two non empty sets then AUB=A nn B iff

If A and B are any two non-empty subsets of a set E, then what is A uu (A nnB) equal to ?

If X and Y are any two non-empty sets, then what is (X-Y)' equal to?

If A and B are two non empty sets the prove the following1.n(AuuB)=n(A)+n(B)-n(AnnB) ." " 2. nAuuBuuC)=n(A)+n(B)+n(C)-n(AnnB)-n(BnnC)-n(Cnna)+n(AnnBnnC)
