A clock has an hour, minute, and second hand, all of length 1. Let T be the triangle formed by the ends of these hands. A time of day is chosen uniformly at random. What is the expected value of the area of T?

"The problem is equivalent to placing 3 random points on a unit circle"
This premise is wrong. Given the position of the hour hand then the positions of the minute hand and second hand are set as a function of the hour hand.
If the hour hand is at angle T (measured clockwise from 12:00) then the minute hand is at angle 12*T and the second hand is at angle 720*T.
