Give an example of two uncountable sets A and B such that A ? B isa) finite.________________b) countably infinite.________________c) uncountable.

Solution Step 1:We have given the two uncountable sets A and B and we need to give the example such that is (a) finite (b)countably infinite (c)uncountable.Step 2:(a) is finiteis finite for uncountable sets A and B.Let A and B be the same sets,set of real numbers then is empty of size zero.then is finite.
