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!

For a uniform probability distribution, you can find the probability of an event using the formula

How Do You Find the Probability an Event in a Uniform Probability Distribution?

For a uniform probability distribution, you can find the probability of an event using the formula P(A) = m / n. Watch this video to learn how this works.

A probability distribution where all outcomes in the sample space have the same probability

P(A) = m / n
where A is the event, m is the number of favorable outcomes and n is the number of possible outcomes

If a die or coin is fair, it is balanced in a way that makes it equally likely to land on each face or side
