You're trapped in a maze. There is a way out. Path junctions are all 3-way.

If you use the strategy of always taking the path going right, what will happen?

(Note: This problem is deliberarely vague.)

(In reply to re(2): Depends. by Cheradenine)

Because of the category, I assumed that the problem was asking what the probability was of the right-hand strategy working. If that is not what you are looking for, I have no idea what your question even means.

As I said the chance of the strategy succeeding is 100% if the wall on your right is part of an outside piece of the maze, and 0% if it is part of an inside piece. So your total chances are dependant on (and in fact equal to) the chance that the wall on your right is an outside piece, which in turn depends on the proportion of outside pieces to total pieces.

Most garden mazes and puzzle book mazes have only outside pieces, and so the right-hand method will work.
