What are the odds you will 5 spins in a row betting on red or black and what are the odds the house will win 5 in a row! First the odds of you winning 5 spins in a row betting on either red or black are 1 in 42 the odds of the house winning 5 spins in a row when you bet on red or black are 1 in 25! The house has a 68% better chance to win 5 in row than you do! Lets expand the streak to 10 spins in a row the 18/38=.4736^10=.000568% or 1 in 1758 the odds for the house to win 10 spins in a row are 20\38=.5263^10=.001631 or
1 in 613! The house is 286% more likely than the player to win 10 spins in a row when the player bets on red or black!
This goes to show you all though the odds of roulette seem when they are 5.26% against you for one spin when make more and more spins you are way more likely to lose.

Every spin is independent anyway, so if you bet you will loose your bet 52.63% of the time and the same is true for the next bet you will make, this is why every kind of progression system will loose exactly the house edge +/- Standard Deviation, this is because every single independent bet have the same chances to loose, therefore after making every kind of bet you have in your system a certain amount of times, you approach the long run and loose 5.26% of everything you bet +/- SD.
