Nevermind. I just have to see when exactly a short circuit appears and I am off to the world of dreams. smile

Re: dice probability

Bobbym Said that he ran simulations.
What software did you use?

Re: dice probability

Hi;

The exact answer is in post #33. The simulations were run using Mathematica in both the procedural and functional styles.

Re: dice probability

Hi bobbym

What is the trick that reduces the possibilities you mentioned before?

Re: dice probability

Unfortunately, I do not remember it. What is bothersome is that there is no analytical answer.

See post #37 for some information about it.

Re: dice probability

Maybe there is an analytical answer and you don't have it.

That is the post I read which made me post #56.

Re: dice probability

I had gAr look at it too so the solution is tough. The idea is not to be stumped even when you do not have an analytical answer.

Re: dice probability

Which guess did you use. The one where the winner is the one who gets the sum >=10 first or the one with the game restarting when a sum is >10?

sum >=10 was given the nod. Juan never returned to this problem.

Re: dice probability

Interesting. Maybe the good old casework can give us the answer.

Re: dice probability

You mean, an analytic one? Because you already had a numerical answer.

Re: dice probability

That is not a numerical answer. It is the exact answer.

You mean, an analytic one?

An answer that only involves the use of gf's.

Re: dice probability

Bad choice of words. An experimental one.

Which GFs?

Re: dice probability

So his probability for throwing a 10 or more is the Dice GF**10 with the terms with x**9 or less power are taken off, you put x=1 and sum over. But what do you do about the other guy?

Re: dice probability

That is too simplistic. The answer may only use a simple gf but it is not simple to write or explain without doing it. It requires a computer to do the expansions.

It will go in computer math as soon as I can condense it to fit in one post. That is, if I can fit it...
