Let a, b and c be arbitrary sets. one of the following statements is true, and one is false. draw venn diagrams for each side of each statement. give a careful proof of the statement which is true, and provide a specific counterexample to the statement which is false. (this a, b and c, and explain why, for the a, b and c you have specified, the statement is false.) means that for the statement which is false, you should specify the sets (a) (a\b)u (c\ b) = (an b)\ c (b) (au b)\ (an b) (a\ b)u (b\ 4).
