The negative of the statement $\sim p \wedge (p \vee q)$ is

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

If the truth value of the statement $p \to (\sim q \vee r)$ is false $(F)$,then the truth values of the statements $p, q, r$ are respectively:

The contrapositive of the statement "If it is raining,then $I$ will not come" is

For any three simple statements $p, q, r$,the statement $(p \wedge q) \vee (q \wedge r)$ is true if and only if:

The statement pattern $[(p \vee q) \wedge \sim p] \wedge (\sim q)$ is
