$\displaystyle \neg p \vee \neg q \vee r$

Can you show some working out because I have no idea how you get that answer. For I got as an answer p ^ q ^ (~r)

4. There is nothing to to work out.
Do you know the rules?
$\displaystyle \neg \left( {p \wedge q} \right) \equiv \neg p \vee \neg q$.
Learn the rules!

5. Haha thanks and I will learn them!
