WebBuffon's needle was the earliest problem in geometric probability to be solved; [2] it can be solved using integral geometry. The solution for the sought probability p, in the case where the needle length ℓ is not greater than the width t of the strips, is.

Therefore T is binomially distributed with n = n, p = P. The variance, var [ T], then just follows: n p ∗ ( 1 − p). Differentiate with respect l then solve.
