I'm testing a piece of perl code (tenuous justifiction :)) that has billions of possibilities and thus is impractical to test exhaustively.

Therefore I want o test statistically, and to that end my question:

Given a (near) perfect PRNG, if I pick two sets of 1e6 random 32-bit unsigned integers:

How much overlap, (how many dups), should I expect between the two sets?
With what standard deviation?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.
