I Average profits and losses on a roulette table

AI Thread Summary
The discussion revolves around a roulette betting strategy based on the Martingale system, where players double their bets after losses to recover previous losses. Participants highlight the inherent flaws in this strategy, particularly the negative expectation due to the presence of zeros on the roulette wheel, which skews the odds away from 50-50. Despite attempts to simulate outcomes with Python scripts, results indicate that players are likely to end up with losses over time, especially when considering the house edge. The conversation also touches on alternative strategies, such as halving bets, but ultimately concludes that no betting system can overcome the house advantage in roulette. The consensus is that the best approach to gambling is to avoid games with a negative expected value altogether.

I waited for one of the thirds to lose six times in a row at Trump Plaza. On the nex roll someone bet on the two thirds that were coming up while I put $100 on the one that lost six times. I won $200. And yes, a third can lose for longer than six times. But the next time you are at a casino, find out for yourself how many wheels have this happen in 5 or 6 hours. Not many.

I waited for one of the thirds to lose six times in a row. On the next throw, a fellow put his chips on both the thirds that were winning for the last six throws. I put $100 on the third that lost six times in a row, right in the middle between his two stacks of chips. I won $200.
See for yourself how many times in a two to five hour period any wheel has one third lose for six times in a row. If this bothers you to make a large bet after six loses, wait until a wheel has one third lose eight times in a row (if you have the patience to wait that long) before betting on the losing third.
I know...the odds of any third or 0 and 00 are the same with each spin. But it seems that runs of length on a losing third do not happen with any kind of frequency. Try it some time. After a couple of hours, track the most number of times a third will lose in a row...

Again, gambler's fallacy.

You are not interested in the first six times - you bet no money on it. You are interested in the odds at the present time, i.e., the odds of getting something seven times in a row given that it has already occurred six times in a row.

So what exactly is your point?
