The Boolean expression $ \sim \left( {p \Rightarrow \left( { \sim q} \right)} \right)$ is equivalent to
$\left( { \sim p} \right) \Rightarrow q$
$p \vee q$
$p \wedge q$
$q \Rightarrow \sim p$
If $P$ and $Q$ are two statements, then which of the following compound statement is a tautology?
If $\mathrm{p} \rightarrow(\mathrm{p} \wedge-\mathrm{q})$ is false, then the truth values of $p$ and $q$ are respectively
The conditional $(p \wedge q) ==> p$ is
$\sim (p \vee q)$ is equal to
The statment $ \sim \left( {p \leftrightarrow \sim q} \right)$ is
