Consider the compound proposition c = ( p ∧ q) ∨ ( ¬ q ∧ r), where p , q , and r are propositions. This is an example of a proposition generated by p , q , and r . We will define this terminology later in the section. Since each of the three simple propositions has two possible truth values, it follows that there are ... here today film
