hi, i've been going through the missing premise drills and i definitely have a better understanding so thank you!
i was wondering though, on the card that says
P: X -> A
C: not A -> B
should the missing premise be not X -> B? the card says that is the contrapositive of the missing premise but i don't understand how.
i was also wondering, on the card that says
P: X -> C
P: not X -> A
C: not A -> Z
the answer is C -> Z, but I was wondering why it couldn't be A -> Z?
