- A factory buys \(10 \%\) of its components from supplier \(A , 30 \%\) from supplier \(B\) and the rest from supplier \(C\). It is known that \(6 \%\) of the components it buys are faulty.
Of the components bought from supplier \(A , 9 \%\) are faulty and of the components bought from supplier \(B , 3 \%\) are faulty.
- Find the percentage of components bought from supplier \(C\) that are faulty.
A component is selected at random.
- Explain why the event "the component was bought from supplier \(B\) " is not statistically independent from the event "the component is faulty".
