Hi,

"Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense" - Buddha?

Hi;

**In mathematics, you don't understand things. You just get used to them.**

**I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.**

You're welcome.

A modified question:

** If only one die is thrown, what's the probability that '12' is seen before '11' ?**

You're welcome.

Another solution for the two dice using Absorbing Markov Chain:

Now, I'm trying to obtain the probability for the players getting '11' and '12' at the same time.

Looks tricky to extract from the present model.

Hi gAr;

Sorry, I think I got confused. I see that Q is a piece of the absorbing chain.

I can recreate the transition matrix from Q and R.

Hi,

Yeah, felt lazy to type the full matrix, it's anyway not that useful for computation of final probabilities.
