From the question the given statement is $(p\wedge \sim q)\rightarrow r$

Now the negation of the given statement is

$\sim[(p\wedge \sim q)\rightarrow r]$

= $p\wedge (\sim q\wedge \sim r)$

[ $\because$ we know that $\sim(p\rightarrow q) = p\wedge\sim q$ ]

So , our answer is $(p\wedge \sim q)\wedge \sim r$
