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?

3/8 or 37.5%

sequence                     Knotted

000,001,010,011          n,n,y,n

100,101,110,111          n,y,y,n
