Real Time System Please answer question (b)

A system consists of three periodic tasks: T = {(8,4), (10,2), (12,3)}. a) Determine the schedulability of the system by means of schedulability test for the EDF algorithm. Be sure to conclude your calculations. (3 marks) b) Construct a schedule for the above task using in the interval (0,32) for EDF algorithm. Label any missed deadlines. (4 marks) c) The parameters of task (8,4) in the above set of tasks is changed to (0,8,4,4). How will this change affect the schedulability of the set of tasks using the EDF algorithm
