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 $p$ and $q$ are true statements and $r$ and $s$ are false statements,then the truth values of the statement patterns $(p \wedge q) \vee r$ and $(p \vee s) \leftrightarrow(q \wedge r)$ are respectively

The contrapositive of the inverse of $p$ $\rightarrow (p$ $\rightarrow q)$ is

The negation of the statement pattern $p \vee (q \rightarrow \sim r)$ is

Find the component statements of the following compound statement:
It is raining and it is cold.

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