Hello

Just been playing Baccarat at a *certain* casino (I won't name if these results could be considered normal)

Basically I was playing mostly 10 hands (though I did up the hands for a bit) and mostly on Banker (a couple on player) and over three sessions I got these results:

1)
Banker 13 won
Tie 2
Player 30

2)
Banker 11 won
Tie 1
Player 17

3)
Banker 15
Tie 2
Player 25

Total:
Banker 38
Tie 5
Player 72

Could anyone of the more mathematically minded people here tell me the likelihood of that happening?

8 DECKS

Player 44.62%
Tie 9.52%

Will check these probs. I had screenshot sometime ago against The Wiz's probs. but have to be close. Anyway be prepared for the "too small sample size" and the SD thus meaningless. Let me total your figures though.----->>>>.EDIT INSERTED:-OOPS,THEY ARE TOTALED:o. Sometimes a small sample size is adequate. Toss a coin 100 times and get 81 heads and 19 tails then worthy of further investigation. Just an example!!

Software Please???:)

It's 6 decks - I realise that the sample size is tiny (116 hands) but I was just so gobsmacked by the results on a game that is quite close to a coin toss

Edit: If we're working on the basis that a 19/81 ratio is worthy of investigation then a ratio of 38/72 would not be (I presume the banker bet bias would not be enough). Silly me.
 
1.The 6 Deck Probs. I Posted Are The Same As The Wiz's As I Wanted And Did
Confirm.

2. I just used 81/19 randomly,lol, and it was posted before I realized your totals were not actually a 4th session as I note in my edit. That said, the fact is some will just railroad sample size and a bad session, end of story, which may or may not be the end result and situation.

Your numbers, imo , indicate a larger sample size should/must be obtained by whatever means and then investigate for possible malfeasance.:cool:
 
Let me guess. It's RTG. I have had many losing sessions betting on banker and mostly there are player results strung up on 5-6 consecutive hands while it doesnt happen for the banker which should have a slight advantage especially when the player has a value of 0-3 against a banker with 4/5 with 2 cards for each.

I believe Slotswizard also encountered the same at RTG and at an one of these casinos I had a look at my logs over several hundred hands where the player came up on top where it also had a 11-hand consecutive winning streak.

To me, Baccarat results at Playtech, MG and Rival seem fair to me. When I played at Crypto software years ago, I got strange results where the outcome did not match the statistics displayed at the table (multi-player table). However, the support staff did not give any answer for this.

That in theory assuming a fair game will occur. Not sure of the exact probability of how often in Baccy and not checking,lol.

With BJ which has a lower house advantage (assuming a fair game), the player can expect to lose 10 consective hands, iirc , every 1500 hands on average. If these losses all occurred with the dealer showing an upcard of 6 each time (~43% dealer bust prob. versus overall ~28%), then Houston we (ok,may) have a problem!!;)
 
The most unlikely event is having at most 43 banker wins or ties in 115 trials (which equals to having at least 72 player wins in 115 trials).
The probability of having max 43 banker wins or ties is binomial distribution: at most 43 succesful trials, 115 total trials, probability of success is (1-0,4463), and you need the cummulative result of the distribution. It happens roughly once in every 12580 trials (each consists of 115 consecutive rounds).

FTR, the WIZ at least says he will not look at anything less than 1 in 10000. Prolly, to keep every Tom, Dick, and Harry, oh Yeah Sally too from flooding him with garbage.

That said, 1 in 10,000 is not the definition of cheating software. There are multiple ways for the software platforms to cheat and 1 in 10000 or fill in the blank means nothing.

I got 1:2154 chance for this many or more player wins, so your data is not strong enough to draw any conclusions. You should play and lose more to build larger data.

My number differs from what gerilege posted because I didn't include ties in the calculation.
