Is there any reasoon why they are not defined RandomGen g => State g a rather than RandomGen g => (a,a) -> g -> (a,g) ?
It's probably because Control.Monad.State belongs to the MTL which is outside Prelude.
On the other hand, if you are using MTL, you'd probably want a more
general signature, like:
(RandomGen g, MonadState g m) => m a
