In order to be able to generate all pages with exactly equal probability you
have to know the cardinality of the set of all pages. Which nobody does,
because it changes all the time.
Assuming you did know how many there were, you'd simply need to build a list
of them all and then use whrandom.choice() to select an arbitrary element.
Assuming you have enough memory to store a list of 12,000,000,000+ elements,
of course ;-)
If you ever do work out a suitable method, please mail me via
