Description

Suppose that we drop a needle of length l at random onto the plane with a set of parallel lines a distance d apart. Buffon's needle problem is to calculate the probability that the needle lands crossing one of the lines. We generalize the problem into a higher dimension as follows. Suppose that we put a needle of length l at random in the space with a set of parallel planes a distance d apart. Then we calculate the probability that the needle is crossing one of the planes.
