Question 261773
Hint: Recall that p -> q is only false when p is true and q is false. Here's the truth table for p -> q.


<table border=1><th>p</th><th>q</th><th>p -> q</th><tr><td>T</td><td>T</td><td>T</td></tr><tr><td>T</td><td>F</td><td>F</td></tr><tr><td>F</td><td>T</td><td>T</td></tr><tr><td>F</td><td>F</td><td>T</td></tr></table>


Use this idea to find the table for ~p -> ~q
