Using the sets \(A=\\{a, b, e, h\\}, B=\\{b, c, e, f, h |, C=\\{c, d, f, g\\}, \text { and }\) \(U=\\{a, \ldots, h\\},\) find the binary representation of each set. $$ A \cap(B \cap C) $$
Find the family of subsets of each set that do not contain consecutive integers. $$\\{1,2\\}$$
Prove each, where \(A, B,\) and \(C\) are any sets. $$A \cap(A \cup B)=A$$
If \(\Sigma\) is a nonempty alphabet, then \(\Sigma^{*}\) is infinite. (Hint: Assume \(\Sigma^{*}\) is finite. since \(\Sigma \neq \emptyset,\) it contains an element \(a\) Let \(x \in \Sigma^{*}\) with largest length. Now consider \(x a .\) )
Let \(A\) and \(B\) be any fuzzy sets. Prove each. $$ (A \cup B)^{\prime}=A^{\prime} \cap B^{\prime} $$
