This is a classic example of a conditional statement "If A then B". The statement "If a deer has no horns, then it isn't a buck" can be rewritten as "If not B, then not A". Translating this into logical form gives us "All A are B", which is equivalent to statement A. Therefore, all bucks are deer with horns.
