Some symbols are missing. I'm assuming you meant to put in a horseshoe symbol like so [tex]p \supset q[/tex]
If so, then the contrapositive of that would be [tex]\sim q \supset \ \sim p[/tex] which is the final answer.
The tilde sign [tex]\sim[/tex] means "not" so writing [tex]\sim q[/tex] means "not q" which is the complete opposite of q.
