In addition, you are given the following precedence relation: ={(P1,P2),(P1,P6),(P2,P3),(P2,P4),(P2,P5),(P3,P6),(P3,P8),(P4,P6),(P4,P7),(P5,P7),(P5,P8),(P6,P8),(P6,P9),(P7,P9),(P8,P9)} a. Construct the Precedence Graph (not containing any redundant edges; also modify accordingly). Use PowerPoint, diagrams.net, or any other app to draw the graph. (15 points) b. Is the system above determinate for all interpretations of its processes? If it is not, add to necessary elements to make it determinate (no graph drawing needed). Explain all of your reasoning. (20 points) 1. Consider a system of 9 processes, P={p1,,p9}. Associated with the system are 6 memory cells, M={M1,,M6}
