In a parallel system with three valves (Figure 2), the valves are redundant. Only one of the three valves needs to function correctly for the system to work, providing a path from input to output. For the system to fail, all three valves must fail. Figure 2. Three valves in a parallel system 2. What is the probability that the parallel system shown in Figure 2 will function correctly? In other words, what is the probability of at least one valve working correctly? 3. Which system (serial or parallel) is the more reliable valve system? Why?
