come out 12s

Spread the love

Well I just recorded 1,047 rolls with 313 of them being come out rolls and out of those 6 were 12s .

Skinny and I have talked about this and he has said that the math says that a come out 12 should come every 36 rolls but this does not seem right to me . I under stand that this is a small number to go by .

On this session it was like one come out 12 for every 174 rolls which is no were near the 36 rolls .

Does any one else see this in a different way ?

Good Rolling.

We are certainly not the math super expert of Skinny, but to us it looks like on the come out rolls with a come out roll being defined as the first roll after a new turn with the dice or the first roll after making your point, you are doing very well on your come out rolls.  On 313 come out rolls a random roller would roll 8.69 12’s.  You rolled only 6 so we would say your are doing very good.  

Just wondering, how many 12’s on the total of 1047 rolls. That might give you a little different result.

More importantly, remember that 1047 rolls of the dice and 313 come out rolls is a very small sample.  The 1 in 36 is for perhaps 5,000 to 10,000 rolls. 

Just a few thoughts from the peanut galley.  

Hope we see you and many of our GTC friends in the casinos soon.

Well said Doc!

I agree with everything you said except for the part about not being a math super expert. 

You’re not bad in my book.

As doc was getting at, don’t mix apples and grapefruits; if you’re looking at comeout rolls, keep looking at comeout rolls.  You stated a stat with comeouts, but then compared it to all rolls.

Also, when discussing with Skinny, and 1 out of 36 rolls being a 12, that’s against the pure math of a random roller.  If you’re throwing with an advantage, you’d be hoping that that stat would be a greater number between 12’s as you’d hopefully be hitting more box numbers than the random curve dictates.

That’s my penny and a half.
