Final answer:
The times taken for worker 1 to perform a task are independently distributed randomly and unrelated to each other.
Step-by-step explanation:
The times taken for worker 1 to perform a task are independently distributed randomly and unrelated to each other.
For example, if worker 1 takes 5 minutes to perform a task, the next time they perform the same task could be 3 minutes, 10 minutes, or any other random duration. The times taken for each task are not fixed, according to a schedule, or in a sequential manner.
