Question 616188: Determine if the argument is valid or invalid. Give a reason to justify answer.
If it is cold, then you need a coat.
You do not need a coat.
∴ It is not cold. Answer by solver91311(24713) (Show Source):
Argument is valid. Contrapositive always has the same truth value as the original statement, i.e. if "if p then q" is valid, then "if not q then not p" is also valid.
