Show answer & explanation
Correct answer: A
First, convert the arrival rate to processes per second. 6 processes per minute equals 6/60 = 0.1 processes per second. Next, calculate CPU utilization by multiplying the arrival rate by the service time: 0.1 processes/second × 7 seconds/process = 0.7. Therefore, the CPU utilization is 70%.
