Final answer:
The critical ratio scheduling rule is used to prioritize jobs based on their expected completion time and deadline.
Step-by-step explanation:
The critical ratio scheduling rule is used to prioritize jobs based on their expected completion time and deadline. It calculates the critical ratio of each job by dividing the time remaining until the deadline by the expected processing time. The job with the highest critical ratio is given the highest priority. In this case, we need additional information such as the expected processing time and deadlines of the jobs in order to determine the sequence.
