We aren't told anything about the intersection of 'Life savers' and 'Bumper Cars', so it's incorrect to conclude that they do or do not intersect. These two Euler diagrams are both valid given the information in the question:The logic puzzles of Rina are confusing. We are told "Last one! Let's get it right. All ambulances are life savers. No ambulances are bumper cars. Then... with "Some life savers are no bumper cars" being the correct answer. Why are "No bumper cars are life savers" and "No life savers are bumper cars" wrong?
ambulances = life savers
no ambulances = bumper cars
ergo
no life savers = bumper cars
What am I missing?
Some bumper cars are life savers and some life savers are bumper cars:
No bumper cars are life savers and no life savers are bumper cars:
You can't tell which of these is true from the two statements in the question.
