Let p and q be two statements. Then $$ \sim \left( {p \wedge (p \Rightarrow \, \sim q)} \right)$$ is equivalent to

The compound statement $$\left( { \sim (P \wedge Q)} \right) \vee \left( {( \sim P) \wedge Q} \right) \Rightarrow \left( {( \sim P) \wedge ( \sim Q)} \right)$$ is equivalent to

The statement $$(p \Rightarrow q) \vee(p \Rightarrow r)$$ is NOT equivalent to

The statement $$(p \wedge q) \Rightarrow(p \wedge r)$$ is equivalent to :
