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?
so tracing the knot from A to B you can note if it crossed Above or Below points 1, 2, and 3
123
AAA = NO
AAB = NO
ABA = YES
ABB = NO
BAA = NO
BAB = YES
BBA = NO
BBB = NO
out of 8 total combinations only 2 chances to be a knot
1 in 4 chances it is a KNOT
3 in 4 chances it is NOT
