Answer 1

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

$\begin{gathered} BrandA=\frac{40}{913}=0.0438 \\ BrandB=\frac{38}{792}=0.0480 \\ BrandC=\frac{21}{626}=0.0335 \\ BrandD=\frac{15}{451}=0.0332 \end{gathered}$

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