Random chord problem (Posted on 2009-05-11) Difficulty: 1 of 5
Pick two points at random on a circle and draw the chord connecting them.

Pick two more points and connect them with a second chord.

What is the probability that these chords intersect?

You're only calculating the probability of crossing that median diameter, not of crossing the original chord.
