  • Which Switch?

    You cannot figure out without a doubt which switch controls the light.


    if I flip one switch and the light is on, I know which switch controls the light, but only by chance.


    If I flip one switch and the light is still off, I don't know which of the two other switches controls the light.


    If I flip two switches and the light is on, I don't know which of the two flipped switches controls the light.


    If I flip three switches once then I am guaranteed the light will be on since I know the light is off to start, but I don't know which of the three switches controls the light.
