|Q2. With respect to lottery scheduling, suppose we have 4 users Ali, Kashif, Junaid and Imran in a system that can only process integer number of tickets. There are total 125 tickets in the system and currently the tickets allocation is Ali=35, Kashif=25, Junaid=45 and Imran=20. The currently executing processes of each user is Ali=7, Kashif=5, Junaid=10, and Imran= 5. (a) What is the probability of execution for each process of all the users? (b) Using ticket inflation reallocate the tickets so that the overall probability of execution for each process of user Kashif is P1= 2%, P2=4%, p3=6%, p4=1.6%, p5=6.4%.
