Goal: 50% heads, exactly. The more flips, the closer you get.
Streaks happen
In 100 flips, runs of 5 or 6 in a row are almost guaranteed. Our brains see streaks as 'unfair' — but they're statistically inevitable.
1000 flips usually settles within ±2% of 50/50. The more trials, the closer you get. That's the law of large numbers, in action.
