Knot or Not? (Posted on 2005-08-04)

I was walking along the road one day when I spied a cord of some sort lying in my path. From my vantage point, as I was approaching the cord, I could not tell if it was knotted or not.

What is the probability that the cord was knotted?

AS there are only 2 combinations of the crosspoint positions (out of 8) which result in the knot ,the probability is 0.25.
