Can the order of execution of fork() be determined?

Question

I\'m working on an exercise on the textbook \"Operating System Concepts 7th Edition\", and I\'m a bit confused about how does fork() work. From my understanding

Answer 1

The process which is selected by your system scheduler is chosen to run, not unlike any other application running on your operating system. The process spawned is treated like any other process where the scheduler assigns a priority or spot in queue or whatever the implementation is.
