Question

The contrapositive of p q is:

Answer 1

Some symbols are missing. I'm assuming you meant to put in a horseshoe symbol like so $p \supset q$

If so, then the contrapositive of that would be $\sim q \supset \ \sim p$ which is the final answer. 

The tilde sign $\sim$ means "not" so writing $\sim q$ means "not q" which is the complete opposite of q.
