I have found a way to get rid of the GF, but it introduces a nasty sum.

What is the sum?

Hmmmm.

For one thing it is useless for computation.

Maybe it can be simplified further.

But that will not help as much as you think.

Hi gAr;

Sorry, did not see you up there.

I think we can't approximate it using e^(5x), since we are using coefficients beyond the upper limit of the egf.

I agree, it did not work.

Hi bobbym,

No problem.

I couldn't find a continuous distribution to approximate it. It's doubtful that a simplification exists, CAS is failing to guess, what more is left?!

Pure dumb luck for me. They say out here, "I would rather be lucky than good!"

Yes, I too must be lucky to find a formula for this!

Hi bobbym

Have you seen the 2's and 5's problem? It seems like a tough one.
