A Stick of length L divided in three parts. What is the probability that three parts can form a triangle ??

The sum of the lengths of the two smaller sides of any triangle is larger than the length of the longest side, so the longest side from the triangle formed in the excersize is less than 0.5L.

You need to specify the probability distribution for the division.
