Different arrangements would do it, or you could think of it very loosely as the “if you made different decisions in each” kind of thing. Events/history is different, essentially.
On your idea of a “random function” yes, pretty much everything at a fundamental level appears to be probabilistic to some level. Quantum theory cannot in most cases predict the exact outcome of an experiment, just the probability of different outcomes.
