WebAn implication and its contrapositive have the same truth-value. That is, proposition p → q and proposition ~q → ~p are logically equivalent. From the above fact, one can easy derive the conclusion that to prove p → q one might just as well prove ~q → ~p, if this is for one reason or another more feasible. WebThe Contrapositive of a Conditional Statement. Suppose you have the conditional statement {\color{blue}p} \to {\color{red}q}, we compose the contrapositive statement by …
