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?
(In reply to
solution, maybe by Stephanie)
your comment caused me to think of a good question. Is the intersection supposed to occur inside the circle or are the chords extended to allow intersection outside of the circle in which case as Stephanie pointed out the only way for them not to intersect is if they are parallel.
