Lets see.

Geni has 8188 edits, 3329 article edits, over 3351 pages.
Sam has 8814 edits, 3542 article edits, over 4708 pages.
I have 8344 edits, 4647 article edits, over 4369 pages.

Lets assume, since those numbers are broadly similar, that we average
out to a statistically normal "heavy user", who has...

8442 edits, of which 3839 (45%) are to articles. These are over 4143
pages, so our user has perhaps edited 1,880 seperate article pages -
call it 2,000.

Q. How many of those highly active users would we need for it to be
statistically likely that one had, at some point, edited each of our
970,000 articles? (5 marks. Show working)
