5. 6. 7. How does a program achieve mutual exclusion using 3 sections of code? Draw a circuit which achieves the following: ((a'+b). (b'+ c)). (b +c). In the circuit from #6, what are the results if a 0, b 0, c 1? 5. 6. 7. How does a program achieve mutual exclusion using 3 sections of code? Draw a circuit which achieves the following: ((a'+b).
