Suppose the control system of a fighter jet consists of three unrelated components in series, and it is desired to have 98% reliability of the system. If the reliability level of all the components is the same, then the reliability of each component (rounded off to three decimal places) is ______ %. |

Answer» Explanation: Let reliability levels of the First, Second, and Third Component be \(R_1, R_2 \: and \:R_3\) respectively. The reliability level of all the components is the same. i.e. \(R_1 = R_2 = R_3 = R\) Now, A fighter jet consists of three unrelated components in series, ∴ \(R_s = R_1\times R_2 \times R_3 = 0.98\) \(R_s = R\times R \times R\) \(R_s = R^3\) \(0.98 = R^3\) \(R = 0.98^{1/3}\) \(R = 0.993\) R = 99.3 % |
