Question: could someone check out part b i am pretty sure...

Question details

Could someone check out part b)? I am pretty sure the given answer is wrong and the real answer should be an empty set. This is in reference to section 1.4 # 2b of How to Prove It 2nd edition. - edit- I figured someone would be able to go to the exact question I was referring to but here it is. When I do part B I get empty set.Step 1 of 4A Consider the following sets, A United States, Germany, China, Australia) B-Germany, France, India, Brazil} C= |x|x is a country in Europe CommentStep 3 of 4 Since, intersection is the collection of all the elements which are common to both the sets Therefore, (AnB) Germany) This implies, (AnB)IC-\Germany) it can be observed from part (c) that ((AnB) \ C) ((Bn C) \ A)-ф . That is, both sets have no element in common. Therefore, the sets ((An)\C) and(Bnc)\A) are disjoint It can be observed from part (a) that Germany is contained in AUB Hence, (AnB)IC is the subset of the set AUB
