Question

I need to know A and B, for both a and b the are rounded to the 8th decimal places as needed

Answer 1

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:

`\begin{gathered} 0.0056\cdot0.0056\cdot0.0056 \\ =0.0000001756 \end{gathered}`

If we round this to the 8th decimal place, this is:

0.0000002
