Anyone remember what that formula for the distribution of prime numbers is?

Am thinking this would be an interesting test for the pseudorandomly generated California Fantasy 5 lottery game. It’s 37 choose five. Easy to convert winning combinations to n in the range of [1, 575757]. Would be nice to know if it’s better to bet on composite or prime #’s.
... had me doubt my RPN calc skills for a moment, but then I looked it up and it's 39 choose five and that matches 575757. 
I don't think it matters because each of the 575757 is equally likely. And you can relabel the 39 nums arbitrarily, which would change which are prime.

Of course they can be mapped arbitrarily! However, this doesn’t negate this or any test of randomness. The tests for randomness are precisely to determine if each are really equally likely. This is the assumption I am testing. We know how a computer choosing randomly fails.

Am trying to determine just how their chosen method(s) fail(s).
