Buffon's Needle Problem
Find the probability 
that a needle of length 
will land on a line, given a floor with equally spaced ParallelLines a distance 
apart.

Several attempts have been made to experimentally determine
by needle-tossing. For a discussion of the relevantstatistics and a critical analysis of one of the more accurate (and least believable) needle-tossings, see Badger (1994).See also Buffon-Laplace Needle Problem
