Document Summary

You know that each card has a letter on one side and a number on the other. At the moment, you can read the symbols e, p , 3, and 8 on the sides that are up. These are interesting, fun logic puzzles, but perhaps beyond the scope of this course. If you get done with the previous four questions quickly, have a go at them: this problems is a classic and you may have heard it before. You nd yourself in a room with two doors. One door leads to freedom, and the other door leads to a deadly trap. One of the guards always tells the truth whereas the other guard always lies, but you do not know which one is which. You are allowed to approach one of the guards and pose her one single yes-no question. After that, you have to choose one of the two doors.
