Or to give a slightly better example, suppose you're playing russian roulette with a six-shot revolver. You empty the revolver of bullets, then put one bullet in, spin the barrel, point it at your head and fire.

What is the chance that you're shot? Is it 1/6? What about if you open it up and look in the barrel to see if there's a bullet there?

Nothing about the location of the bullet has changed.

Are you suggesting this example somehow shows that changing knowledge/probabilities determine whether what's going on there is deterministic or not, as is the issue under discussion?
