Take a stick of unit length and break it into three pieces, choosing the break points at random. (The break points are assumed to be chosen simultaneously.) What is the probability that the three pieces can be used to form a triangle?

Hint: The sum of the lengths of any two pieces must exceed the length of the third, so each piece must have length [math] \lt 1/2[/math]. Now use Exercise(g).
