Fibonacci numbers and the probability of polygon formation using random length sticks

Mark Brennana, Noah Callow, Tian Cao Lin · 2026

We present two complementary proofs that, if the lengths of $n$ sticks are sampled at random, then the probability that no $p+1$ sticks can form a $(p+1)$-sided polygon can be expressed as the product…
