From a point on the circumference of a circle of radius a, a chord is drawn in a random direction (all directions are equally likely). 4a and that the TC Show that the expected value of the length of the chord is variance of the length is 2a' (1 – 8/n). Also show that the chance is that the length of the chord will exceed the length of the side of an equilateral triangle inscribed in the circle. /
