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.)
I DOUBT THAT THISIS RIGHT
but you can look anyways
the maze can be thought of as a TREE with THREE CHILDREN
picture of tree here
probability of right hand side being the end
= 1/number of end junctions
1/3 chance with 1 junction
1/27 with 1 junction and 3 children
...
you probably wont get out.
