Right, so you agree that on selecting say 1 million natural numbers at
random, using the uniform distribution you're providing, the mean value
of this million natural numbers will be found to be something. My
question is: what is that something? What will the mean value of these
numbers be?
sum(k=1 .. n) k . 1/n = n(n+1)/n/2 = (n+1)/2 . Where n = 1,000,000 .
What's your problem?

Probably that choosing a million numbers at random from the set
of naturals is unlikely to producethe set of numbers
{1,2,3,...,1000000}.
