What is the probability that a randomly drawn chord will be longer than the radius of the circle?

Prove it.

88%, divide the circle in two halves. The chord that is equal to the radius is at 30, that is pi/6, because u only consider one way and one half, the probability for a chord to be smaller than the radius is 2*(180/3)=12%, the remaining is the probability for a chord to be al least equal to the radius.
