CSCI 430 PLEASE HELP THANK YOU

Question 28 (15 points) With processes in memory at once, the probability that all processes are waiting for I/O (in which case the CPU will be idle) is p pr where is the number of processes (or the degree of multiprogramming), and P is the fraction of time that a process spends waiting for I/O to complete. If we assume this probability, then it follows that CPU utilization = 1 - pp 1. li a multiprogrammed system has 8 degrees of multiprogramming (i.e. 8 programs in memory), and each process spends 70% of ils time waiting for 1/O. what will be the CPU utilization? 2. If we have 14 programs in memory and the goal is to insure 97% CPU utilization, what is the maximum I/O wait percentage/ratio that can be tolerated
