Question
This is my first time posting a question. I really enjoy the scientific statistics and the discussions.When I look at the statistics and odds, the odds of 10 bankers happening in a row is around 0.00058. I have downloaded the 1000 game simulations that has been provided in the site. I have seen these strings happen way too often. For example in games 121, and 129 the strings of 10 bankers has happened. In games 13, 38, and 136 string of 10 players have happened. Could you please elaborate on the odds, and why this is happening so often.
Thanks

You seem to be saying that the 1,000 Real World simulations is not in exact accord with expectations... should it be?
Also if you convert 00058 to a percent for 100 games and then multiply by ten for 1,000 games, its not so rare to have a streak of ten.
This would make for a good thread in a forum.
I can make one if you do not know how after NCAA Basketball tonight.
Are you counting the ties in the streak, meaning a tie breaks the streak? That will change the probabilities a bit.
How did you get 0.00058?
This does not look right.
Banker win prob
In an 8 deck game
0.458597^10 counting ties 0.000411445
0.50682483^10 not counting ties 0.001118353
In a 6 deck game still real close values.
I gots to run. so add some comments from my questions and maybe start a new thread.
Counting ties in 8,000 hands (about 1000 shoes)
(Per shoe probabilities are even a bit smaller. I do not have those results with me at work.)
For Banker
expected # of runs 1.78
at least one 10 run 0.832105832341954
at least 2, 10 run 0.531808302991253
at least 3, 10 run 0.263956469967264
For Player
expected # of runs 1.39
at least one 10 run 0.750518832600418
at least 2, 10 run 0.403513638543370
at least 3, 10 run 0.162821896198648
Not counting ties coming later
The above numbers are not correct. The problem of being in a hurry
From The Wiz 1,000 8 deck shoe
I get
83,640 hands
(streaks are Not counting ties
This is per shoe)
For Banker
expected # of runs ~43.1
actual 41
For Player
expected # of runs ~33.1
actual 31
Counting ties in 1000 shoes coming later
