The aircraft works when at least one of its components works
Probability of failure, f = 0.0056
Probability of success, s = 1 - 0.0056 = 0.9944.
If we suppose that all the three components fail, the probability of this event will be:
[tex]\begin{gathered} 0.0056\cdot0.0056\cdot0.0056 \\ =0.0000001756 \end{gathered}[/tex]
If we round this to the 8th decimal place, this is:
0.0000002
