Markov-Models

1. What is the reliability of the system modeled with the following reliability block diagram. Assume that the reliability of each component is R(Ra,Rb...) and the components fail independent of each other.

2. If all the modules are identical, characterized by the same reliability R, express Rsystem as a function of R. Express the final result in the polynomial format.

3. If the reliability of each module is R=0.39, calculate the reliability of the system Rsystem
