Pattern Recipe Lab

Combine primes, squares, Fibonacci numbers and sums. Count how much of chance your recipe describes.

Choose a ball game with established pool rules: 1–8 numbers drawn, with labels from 1 to 100. An observed maximum alone is insufficient.

∑The maths, in plain language

✦The story behind it

Categories can overlap. Their joint counts use four disjoint groups. Adding sums or last-digit rules enumerates at most 250,000 combinations, then uses 60,000 seeded draws. A zero sampled count still has uncertainty. These are model probabilities, not evidence of bias or predictions.

P(R=r) = C(M,r) C(N−M,k−r) / C(N,k)

NIST · Hypergeometric distribution

Prime, square and Fibonacci labels describe numbers; they do not make a fair ball more likely. Build a recipe before looking at a draw, then ask how many other combinations fit it.
