Final answer:
To determine the reliability of the system, multiply the reliabilities of each component.
Step-by-step explanation:
To determine the reliability of the system, we need to multiply the reliabilities of each component.
Given:
- R2 backup = 0.81
- R3 backup = 0.91
- R1 = 0.85
- R2 = 0.92
- R3 = 0.77
To find the reliability of the system, multiply all the reliabilities:
R_system = R1 * R2 * R3 * R2 backup * R3 backup
Substituting the given values:
R_system = 0.85 * 0.92 * 0.77 * 0.81 * 0.91 = 0.448
Therefore, the reliability of the system is 0.448.
