Problem #14: Is the Rope Knotted?
A loop of rope is lying on the ground in the position show in the figure below:
You are too far away to see which section of the rope is above or below at each
of the crossovers at A, B and C.
If we assume that it is equally likely that
either section is on top at each crossover, what is the probability that the
rope is knotted?
