I find those two puzzles to be rife with ambiguities. First, a "force" is not going affect the attitude; only a torque will do that, and as another poster has noted, there's a bit of a difference between "random force" and "random attitude". There's also the question of just what "random" means. The word "random" just means that there is some probability distribution; it does nothing to tell us what it is. Finally, there's the issue of starting orientation. If the needles start out vertical, then the most likely result is that they will end up vertical.
