On the Conditional Possibilities and Certainties Drill on page 2-59 I am missing the difference between creating the contrapositive and making a mistaken reversal.
For instance on question #4 - if (-N) = o, then what is the contrapositive?
Is it (-o)=N? From my review of the answer it seems this is a mistaken reversal.
So what is the contrapositive?
Thanks, Tamra
