I don't know, nor do I care. I've been playing craps for more than 20+ years and I've seen all kinds of strange things happened with dice and dice combinations. I've seen players bet the 12 for $100 for 40 rolls in a row and never hit it. But after their $4000 was gone the next shooter rolled 12 three times in a row. And I saw a player lose $100,000 at the table making only one bet: hopping the 7 on the come-out with $100 on each of the 7s -- and the dice went around the table all night long and no one had a natural on the come out roll.
What you show me when you roll two dice only shows me what happens when you roll two dice and it doesn't answer the question.
