Expert Solution
Step 1

We need to complete the formal proof of this contrapositive:

                          1. ~P→Q

                           Thus,

                          2. ~Q→P

Note: We need to use -> (dash-greater than) for arrow and # for contradiction.

           And from the given boxes it can be observed that sub-sub-proof.

Also, note that we are not asked to restrict the number of steps to be 7.
