$s:$ If $x$ and $y$ are integers such that $x > y,$ then $-x < -y.$

Given the statement: "If you live in Delhi,then you have winter clothes."

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

Write the following statement in the form "if $p$,then $q$":
$p$: It is necessary to have a password to log on to the server.

If $p \to (q \lor \sim r)$ is false, then the truth values of $(p \leftrightarrow q) \land r$ and $\sim p \to \sim q$ are :
