There are six cards on the table (faces down). We know that two of them (and ONLY two) are Kings, but we do not know where they are. Let's imagine that you pick two cards randomly and turn them. Tell me, which is more probable:
- that at least one of them will be a King; or
- there won't be any Kings among them.
Why? How did you come up with the solution?
Please don't tell me that you were just guessing because I will not accept that! :-)))))
