Münze: Wahrscheinlichkeitsstunde, kein Urteil

Nach vielen Köpfen bleibt der nächste Wurf etwa 1/2.

Independence

Past fair tosses do not change the next probability. Ten heads still leave about 1/2 (fair model). The feeling that balance must be restored is the error.

Streaks and patterns

HHH is 1/8; HTH is also 1/8. A pretty pattern is not rarer. Same illusion as lottery number shapes.

Physical bias

Worn rims, a pre-spun wrist, dropping instead of catching. Labs have reported small face bias. That is not casino-grade RNG. The toy below is browser randomness for play.

Split from the oracle

The yes/no oracle is a decorated question toy. This page is a probability lesson. Neither verdicts destiny. Do not stop a drug or sign a contract on a coin.
