Suppose you have a floor made of parallel strips of wood, each the same width, and you drop a needle onto the floor. What is the probability that the needle will lie across a line between the two strips?

This is a famous problem called Buffon’s Needle, formulated by the French mathematician Georges-Louis Leclerc, Comte de Buffon. The solution to the problem involves the uniform probability distribution. The formula to find the probability even includes the mathematical constant pi!
