Question

If p and q are two statements, then $\sim (p\wedge q)\vee \sim (q\iff p)$ is

• A. tautology
• B. contradiction
• C. neither tautology nor contradiction
• D. none of these

Answer 1

The correct option is C

neither tautology nor contradiction

$S=\sim (p\wedge q)\vee \sim (q\iff p)$
$\begin{array}{ccccc}P& q& \sim (p\wedge q)& \sim (q\iff p)& S\\ T& T& F& F& F\\ T& F& T& T& T\\ F& T& T& T& T\\ F& F& T& F& T\end{array}$
