I just witnessed 21 straight spins on Roulette with no red. It either game black or green. Saw a guy lose $15,000 betting red during what I consider one of the biggest non red run outs ever. Can someone figure these odds for me?
The above two posts answer the question about it happening in the next 21 spins.
Some questions:
- how many spins did you watch? If you watched 1000 spins, then the chance of this streak of non-red happening is about 1/1500.
- how often does this guy play roulette? If he plays 3 hours one wheel every day then the chance of seeing it in a given year is about 1/30.
Yeah this is pretty damn unlikely. But it happens.

And multiply by two since streaks of non-black would have triggered the same post as streaks of non-red.
