Step 1
In propositional logic, \( \Delta(F) \) usually refers to the set of all propositional variables that appear in the formula \( F \). In this case, the propositional variables that appear in \( F \) are \( A, B, \) and \( C \). Show more…

Find the dual of each of these compound propositions. $$ \begin{array}{ll}{\text { a) } p \wedge \neg q \wedge \neg r} & {\text { b) }(p \wedge q \wedge r) \vee s} \\ {\text { c) }(p \vee \mathbf{F}) \wedge(q \vee \mathbf{T})} & {\text { b) }}\end{array} $$
