Hi,

Okay.

I'll try it again!

Hi gAr;

Let me know how you do.

Hi bobbtm,

Yes, if I'll be able to...

Even if you do not, you will at least have the formula. Sometimes that is all we can hope for.

Hi gAr;

It might be possible with the condition of the problem being restricted to just the normal distribution that there may be something simpler. I know that if both numbers were drawn from the same distribution there is a much shorter form.

Hi;

Seems that only occurs when the distributions are the same and the parameters too.

I did not get it. Are we talking about the formula?

Hi bobbym,

Okay.

I think I would have never guessed of a formula like this!

Hi gAr;

Although it is sort of obvious that something has to be multiplied here and we are dealing with two distributions which are computed by integration. I still do not get it either.

I have come across some work by D. Zeilberger on what he calls The Holonomic Ansatz. The Birkhoff - Trijinsky method for getting an asymptotic form from a linear recurrence is part of it. I have not looked at it well enough and I am still researching it so I do not have anything yet.

I have the result, but I do not yet know how to get it.

Hi bobbym,

Thanks for the information.

I too will look around... Interesting problem!

Hi bobbym,

Just finished with the exams, some time to relax for a few days!

Bought two books last week: "Applied combinatorics" by A.Tucker and "Probability, Random Variables and Stochastic Processes" by Papoulis.

How are you?

I am just the same. The Tucker book is excellent! You will enjoy reading that.
