I would say 100% unless he decides to not to go anywhere

not the way u r thinking.he actually doesn't know the exact direction.

1/3? (You obviously wouldn't go the way you came!) Am I right?

didn't the riddle say the probability of him taking ANY one of the roads.
So he is going to take a road, so wouldn't it mean an 100% chance of taking any road?

The stress is on choosing any ONE of the roads... its like, if I put two coins in front of you, and bet on the fact that you'll choose the right one, or something like that, and you are choosing one of the coins randomly, don't I have 50% chance of winning the bet? Its just like that... Suppose Ragib bets he'll go right, I bet he'll go left, and you bet, he'll go forward, what are your chances of winning?
