Question

Draw Venn diagrams for AUB =A U B U C A ∩ B ∩C= ø A – B= A + B

Answer 1

Union of Sets

The union of A and B is the set of all those elements which belong either to A or to B or both A and B. ... Now we will use the notation A U B (which is read as 'A union B') to denote the union of set A and set B. Thus, A U B = {x : x ∈ A or x ∈ B}.
