In the case of SM64 however, only the collision detection code is affected by this floating point arithmetic, but not the rendering engine. So there actually are some differences between the “parallel universes” in SM64. In particular, when Mario moves to a different parallel universe, the same collisions are still detected, although he is rendered as floating in an empty space. We can encode this also in Bobs world:

For N=4N = 4N=4: 4×1/8=1/24 \times 1/8 = 1/24×1/8=1/2. That matches our simulation. But we can only add probabilities when the events are mutually exclusive (no two can happen at the same time). Can two of these events overlap?
