Statistical Confidence & Normal Approximation in 1,000 Flips
At $N = 1,000$, the discrete binomial distribution closely matches the continuous normal distribution $N(\mu = 500, \sigma^2 = 250)$:
μ = 1000 · 0.5 = 500 | σ = √(1000 · 0.5 · 0.5) ≈ 15.811388 Flips (1.58%)Historical comparison: French naturalist Comte de Buffon (1777) tossed a coin 4,040 times to record 2,048 heads (50.69%), mirroring the exact variance predicted by our 1,000-flip Gaussian model.
