(D) Given statements:$p :$ It is raining today.$q :$ $I$ go to school.$r :$ $I$ will meet my friends.$s :$ $I$ will go to watch a movie.Negations:$\sim p :$ It does not rain today.$\sim q :$ $I$ do not go to school.The statement is: 'If it does not rain today or $I$ do not go to school,then $I$ will meet my friends and go to watch a movie'.This can be written as: $(\sim p \vee \sim q) \Rightarrow (r \wedge s)$.Since $(\sim p \vee \sim q)$ is equivalent to $\sim (p \wedge q)$ by De Morgan's Law,the statement can also be represented as $\sim (p \wedge q) \Rightarrow (r \wedge s)$.

If $p :$ It is raining today.
$q :$ $I$ go to school.
$r :$ $I$ will meet my friends.
$s :$ $I$ will go to watch a movie.
Then write the statement: 'If it does not rain today or $I$ do not go to school,then $I$ will meet my friends and go to watch a movie' in symbolic form.
