Best ResponseYou've already chosen the best response.0Let \(A\) and \(B\) be two sets with universal set \(U\). \(A\subseteq B \implies \forall x\in A, x\in B\) (everything in \(A\) is in \(B\)) \(A\cup B := \{x\mid x\in A \vee x\in B\}\) (All the stuff in both sets) \(A\cap B := \{x\mid x\in A \wedge x\in B\}\) (only the stuff that is in both \(A\) and \(B\)) \(A^C=UC:= \{x\mid x\in U\vee x\notin A\} \) (All the stuff that is not in \(A\)) \(\mathcal{P}(A)=\{S\mid S\subseteq A\}\) (the set of all subsets of \(A\))
