Average turnaround time of processes, and how many processes you expect to see waiting, on average, and in ready queue

Please Explain Step by step CLEARLY

Assume processes arrive to the CPU based on a Poisson distribution with an arrival rate of 5 processes per second. Assume also that the service times are exponential. Given that the CPU is, on average, busy 70% of the time. What is the average turnaround time of these processes? How many processes you expect to see waiting, on average, in the Ready Queue? 14 pts] Assume processes arrive to the CPU based on a Poisson distribution with an arrival rate of 5 processes per second.
