Of course! I plan doing it. Let me try the zeta(3) series.

Thanks! And thanks for the converger. I'll try and figure it out.

I got it from some site but do not remember where. Thought it was an oddity at first but found that it really can work.

No problem. I will try understanding it, but it seems complicated...

They claim it is based on Pade Approximants using Chebychev polynomials but I do not see it. Their method 2 is also interesting.

New Problem

We have the numbers S={1,1,1,1,2,2,2,2,3,3,3,3,4,4,4,4,5,5,5,5,6,6,6,6,7,7,7,7,8,8,8,8,9,9,9,9,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10}

Eight numbers are drawn randomly from S without replacement. What is the probability that the 3 highest numbers sum to 30?

A says) It is quite rare, less than .05.

B says) Not really, it is quite common.

C says) I am getting .05 too.

D says) According to my calculations it is 2.25, but I think that is a little low.

E says) It is almost 1 / 2.

### Re: Is this cool with you?

Continuation:

What is the probability if the highest 3 numbers are (9,8,3)?

A says) 352/17917575

B says) Very good!

C says) Why, that is wrong.

D says) Hah! For the first time A and B agree and they are both wrong!

E says) I failed to get a solution that agreed with my simulations.

### Re: Is this cool with you?

Does it ask the probability of three highest numbers being (9,8,3)?

When sorted, it must be  * * * * * 3 8 9 ?
