Section 01 — Gaussian Coin Flip Board
Intuition
Each flip is ±1 (heads or tails). Run thousands of independent trials and watch the Central Limit Theorem emerge — the sum of random variables converges to a bell curve regardless of the underlying distribution. This is the foundation of all Monte Carlo reasoning.
Coin bias (p heads) 50%
Flips per trial 50
Number of trials 2,000
Sum distribution across all trials

Mean = n×(2p−1)  |  σ = 2√(np(1−p))  |  As n→∞ the histogram converges to N(mean, σ²) regardless of p. This is why miners can model revenue as a Gaussian even though each block find is a Bernoulli trial.

Section 02 — Monte Carlo Estimation
Convergence
The core MC loop: sample uniformly, evaluate a condition, aggregate the fraction. Here we estimate π by checking whether random points land inside a unit circle. Watch the 1/√N convergence rate — doubling samples halves the noise, not halves the error.
