Answer :

This is a problem on experimental probability.

The probability from the sample of selecting a faulty MP3 is

[tex]Pr(\text{faulty Mp3)=}\frac{7}{50}[/tex]

We can also use this as a guess to how many are likely to be defective from the whole sample.

It will also be ;

[tex]\begin{gathered} \frac{7}{50}\times2000 \\ =280\text{ MP3s} \end{gathered}[/tex]

Therefore, 280 MP3s are likely to be defective in the shipment.
