The term "every possibility" may be resticted to the quantum level. I am not sure if you were assuming that, or if you were putting the possibility level at the 50/50 chance of a coin flip. I don't think the latter situation is necessarily a foregone conclusion. Maybe this is a bad example, but I could design a coin-flipper machine based on physics that makes one flip and always lands in the same side as it started. If it did not turn up the same, it would be called a miracle, because it would have to violate the laws of physics routinely in your example.
Your statement leads to another thought, however: What if you are right at some micro level (quantum or less?) that results in the consistency that you describe in a particular universe, and that consistency is what we call the laws of physics? Thus, another universe with different consistencies (patterns of probability) would have different laws of physics.
