A little help

[hellakytta84]

Anyone hear willing to help with some maths?
I would appreciate some help with the following scenario,
Playing a single zero wheel and betting on 1 dozen over a 15 step up as you lose progression, mathematically how often can I expect to bust, or lose 15 times in a row?

(25/37)^15 = 0.0027777.
This is rather close to 1/359,
So if you made one attempt every day,
you should expect to go bust once within a year.
UP as you lose would bring you DOWN in the long run!

It is just what scepticus wrote, the maths of the roulette is a tool. 15 Bets in a row is a system. Every short run sample has about 50% chance on a loss or profit. 15 Spins are to less in this case. Has a dozen not appear for more than 10 spins, I expext a profit in the next 15 spins.
A strategy can beat the roulette.
The roulette must spin. aplayer may play!!!
