Suppose that a point is chosen at random on a stick that has length 15 inches, and that the stick is broken into two pieces at that point. Find the expected value of the lengths of the two pieces.
Can anyone help me set this one up???

so the lengths are X and 15-X.
Since we have and as the two expected lengths.
