Math Question for Ganchrow/Durito

[Johnny 55]

I know you guys get semi-erect for any math question and mine is quite rudimentary but I would really appreciate it if you could answer it all the same, probably take you about 5 seconds of computation.

What is the probablility/odds of losing a game 21 times in a row when in each game you have exactly a 25% chance of winning?

0.75 ^ 21, or about 0.24% chance (or about in 400 sequences).

Hmmm

Hmm makes me wonder if I should look into a martingale system where I only bet bigger than +300 dogs!
