Here is a Venn diagram with three sets A, B, and C. Seven (non-intersecting) subsets are labelled with the lowercase letters a, b, c, d, e, f, and z. Each subset includes all the white space up to the first black-line borders, but does not cross any black-line border. u d a b A B Consider each set expression and select all the named subsets included in that set. (AUC) B ( BA) UC (A - B) - C (AUB) - C (AUC) n (B(AUC)) O subset a subset a subset a subset a O subset a O subset b O subset b subset b subset b O subset b O subset c O subset c subset c O subset c O subset c subset d O subset d O subset d O subset d O subset d O subset e O subset e O subset e O subset e O subset e subset f subset f subset f subset f subset f subsetz O subsetz O subsetz O subsetz O subset z
