removeBuffon's needle problem asks to find the probability that a needle of length l will land on a line, given a floor with equally spaced parallel lines a distance d apart. the problem was first posed by the french naturalist buffon in 1733 (buffon 1733, pp. 43-45), and reproduced with solution by buffon in 1777 (buffon 1777, pp. 100-104). define the size parameter x by x=l/d.
