From time to time, I get asked these type of questions, when someone reads about something like this on one of the boards! The posters said he rolled 15 field numbers in a row. I guy that is asking me wants to know if I've ever seen someone do that!

My answer was no in all my years of playing craps that is one that I've not seen happen! So for all you math guys that we all depend on so much, what would be the odds of rolling 15 field numbers in a row?

The short answer is this: There is a 16 / 36 = 0.444444444 chance that the NEXT roll is a field.

There is a ( 16 / 36 ) ^ 15 = 0. 0.000005215 chance that the NEXT 15 ROLLS are all fields. (i.e. 1 in 191,751)

The chance that you'll see such an outcome at all? That really depends upon how many rolls you see...

Agree with DJ here
very next 15 rolls or any set of 15 rolls in a row
0.000005215095051
1 in 191,751.059

Now...
at least 1 time in the next 150 rolls
0.000396285480908
1 in 2,523.433

at least 1 time in the next 1,500 rolls
0.004298595447968
1 in 232.634

at least 1 time in the next 15,000 rolls
0.042493558426407
1 in 23.533

at least 1 time in the next 150,000 rolls
0.352458584520565
1 in 2.837

1 million rolls
0.944831707413646

The average number of dice rolls to see 15 in a row is
345,150.11
Meaning one just keeps rolling the dice until the event happens

I personally in about 10k rolls have had 2 steaks of 12 in a row Field hits.
No one bet the first one (The Strat)
Many bet the 2nd one (El Cortez)
at least 2 runs of length 12 or more in 10k rolls
0.043690201836681

By the time I had a post composed, not only had Dave given his answer, but Russ had complained about it. All I could add is that the chance of getting exactly 15 straight (and then getting a non-field number on roll #16) would be:

P= 2.897 x 10^(-6) or about 1 chance in 345,152.

Question: "I just saw a guy roll 15 field winners in a row! What are the odds of that happening?"

My smartass answer: "One. Because you just saw it happen."

The thing that throws most folks is that the, "15 field rolls in a row" that has already occured, does not alter the probability of a field number on the next, or any future rolls. The "odds" provided in the answers above (except the streak calculations), specifically refer to a future 15, (and only 15) rolls of the dice.

I saw exactly 15 Field Numbers thrown in a row in Atlantic City in the early 2000s.

Not much is impossible in Craps, improbable not impossible. In my 12 years of playing Craps; I've seen so many anomalies on a Craps table...there's not much I won't believe.
