3. The inverse is: p!: q. In Table 5 we compare the truth values of these propositions. Table 5: The truth table for the implication, contrapositive, converse, and inverse. p q!:!: TTT T T T TFF F T T FTT T F F FFT T T T We say that two compound propositions P and Q are logically equivalent if they have the same truth values. We shall write P Q ...
