What is the contrapositive of the following statement? “If it is not a lion, then it is a cat.” If it is not a cat, then it is a lion. If it is a cat, then it is not a lion. If it is a lion, then it is a cat. If it is not a lion, then it is not a cat.

Statement if P then Q Contrapositive if not Q then not P

OpenStudy (anonymous):

is it b

Parth (parthkohli):

No, that'd be the converse, not the contrapositive

Parth (parthkohli):

another way to think about it is to find the inverse of the converse
