FIND THE RIGHT DOOR

1,480.0K Views

You are trapped in a room with two doors. One leads to certain death and the other leads to freedom. You don’t know which is which.

There are two robots guarding the doors. They will let you choose one door but upon doing so you must go through it.

You can, however, ask one robot one question. The problem is one robot always tells the truth ,the other always lies and you don’t know which is which.

What is the question you ask?

    Ask one robot what the other robot would say, if it was asked which door was safe. Then go through the other door.

    —Ask one robot what the other robot would say
    Positive Negative = Negative  (Truth Lie = Lie)

    —- Then go through the other door.
    And opposite of Negation = Positive (Opposite of Lie = Truth)
