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.
