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

Negation of the statement $(p \vee r) \Rightarrow(q \vee r)$ is :

The statement $\sim(p\leftrightarrow \sim q)$ is :

The negation of the statement $q \wedge \left( { \sim p \vee  \sim r} \right)$

If $p \to ( \sim p\,\, \vee \, \sim q)$ is false, then the truth values of  $p$ and  $q$ are respectively .

Among the statements

$(S1)$: $(p \Rightarrow q) \vee((\sim p) \wedge q)$ is a tautology

$(S2)$: $(q \Rightarrow p) \Rightarrow((\sim p) \wedge q)$ is a contradiction
