Answer 1

Step-by-step explanation

To find the brand that should be eliminated, we must find the probability that a brand is returned.

`\begin{gathered} P(return)=\frac{number\text{ of returns}}{total\text{ sold}} \\ \end{gathered}`

Therefore

`\begin{gathered} BrandA=(40)/(913)=0.0438 \\ BrandB=(38)/(792)=0.0480 \\ BrandC=(21)/(626)=0.0335 \\ BrandD=(15)/(451)=0.0332 \end{gathered}`

From the above, we can see that the Brand that is most returned is Brand B.
