Chance of rolling a seven is 6 out of 36, or .16667.

Chance of rolling any other number 30 out of 36, or .83333.

Say you roll any number other than 7, the chance of a second roll being anything other than a 7 is again .83333.

So is the chance of two rolls in a row being any number other than 7 .83333 to the second power?

And the chance of three rolls in a row no seven .83333 to the third power?

If my calculations are correct, the chance of 10 rolls without a seven is .83333 to the 10th power, or .16151.

Am I right?

You bet! What is the next question!?

So the chance of 10 rolls without a 7 is just slightly less than rolling a 7: .16151 compared to .16667.

If I'm playing crapless craps and get 10 rolls without a 7, what is the expected payout of those 10 rolls?

2 and 12 pay 11 to 2, 3 and 11 pay 11 to 4.

(Edited to change 2 and 12 pay 11 to 2, not 11 to 4)

. Not sure what you are asking? What were you betting on?Quote:HeadlockThanks Soopoo.

Quote:HeadlockI realized last night when I was in bed reviewing the day that I did not give enough information. So lets say $260 across. $25 each except $30 on the six and eight.

So your question is, given the shooter threw 10 non-seven numbers, what’s the expected winnings of this ten throws?
