Four points W, X , Y, Z  are chosen at random on the circumference of a circle. What is the probability that the segments WX and YZ intersect?


Don't know how to approach? I suspect finding the probability of  cases where they don't intersect and then subtractiing from 1 would be easier?

Using calculus, the answer is 1/2.
