gAr's series can be stated in words. Take two lists of equal lengths of the throw of a single die. Add all the elements inthe first list to get s1. Then add all the elements in the second list to get s2. Now get the absolute value of s1- s2.

He is not asking for the average difference, but for the expected sum.

Well, if the average difference is 35/18, then wouldn't it be logical that the average sum of those would be 123456787654321?

If we throw the dice n times the answer will be n*35/18.

Hi Boby

I do not agree, but it does seem right at first!

We had a guest poster who styled himself Boby.

He posted the entire contents, adobe graphics encoding included, from a random pdf. And just to make sure we noticed, he posted it three times.

I think Stefy is being ironic.

Hmm... The only way you could bar a guest is by IP, and that gets you nothing if he gets another computer to work on...

True enough but there are other ways to deal with them. I am pretty much sure it is one juvenile imbecile who is entertaining himself.

I deleted the posts. Would it be better if I just alerted you so you could do a more lasting zap?

No, you did the right thing. I prefer the action of stopping them immediately.
