Buffon's Coin Problem

Background: Georges-Louis Leclerc, Comte de Buffon (1707 1788) was a french mathematician and naturalist. He began the study of geometric probability with his coin and needle problems. Geometric probabilities are computed by the comparison of measurements.

Geometric Probability
involves the comparison of measurements to compute probabilities.
