WebCase 1. Suppose :(p!q) is true and p^:qis false.:(p!q) would be true if p!qis false. Now this only occurs if pis true and qis false. However, if pis true and qis false, then p^:qwill be true. Hence this case is not possible. Case 2. Suppose :(p!q) is false and p^:qis true. p^:qis true only if pis true and qis false. But in this case, :(p!q ... Webtrue". Thus, :(p^q) is true exactly when one or both of pand qis false, that is, when :p_:qis true. Similarly, :(p_q) can be seen to the same as :p^:q. Our reasoning can be checked on the truth tables below. Observe that the pairs of statements in question have the same truth value given any combination of possible truth values of pand q.
