Consider a parallel system consisting of three components, where the failure rate of each component is $\lambda$. Answer the following questions. a. What is the MTTF of this system? Simplify your answer to a final expression. b. Assume the three parallel units are connected to a majority-voter. If the reliability of each component is $\mathrm{R}$ and the reliability of the voter is three times the reliability of a component, what is the expression representing the reliability of this new system?
