The negation of $\sim s \vee (\sim r \wedge s)$ is equivalent to :

The negation of the Boolean expression $p \vee (\sim p \wedge q)$ is equivalent to

Negation of $p \wedge (\sim q \vee \sim r)$ is -

$\sim(\sim p \rightarrow q) \equiv$

Consider the following two statements :
$P :$ If $7$ is an odd number,then $7$ is divisible by $2.$
$Q :$ If $7$ is a prime number,then $7$ is an odd number.
If $V_1$ is the truth value of the contrapositive of $P$ and $V_2$ is the truth value of the contrapositive of $Q,$ then the ordered pair $(V_1, V_2)$ equals
