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.)

"Essentially, what you've just "proven" is that the average random maze, regardless of size, has exactly two loops.
nope, ive proven that a RIGHT HAND LOOP in a random maze has on average n/2 paths. so a random maze
will ON AVERAGE have two RIGHT HAND LOOPS. the maze can have more/different loops if you follow other strategies.
"I challenge you to draw any maze satisfying the 3-path condition with more than two nodes for which this is true."
