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 %
