Default Re: Pure probability question

Followup: Suppose you add the numbers up until you get 1000. Roughly how many do you expect it to take?

It's easy to see that the average is a bit more than 2000. Here is a hint: The average is about 2000+a/b, where a and b are small integers. Of course, the problem is not just to determine a/b, but also to justify it.
