#### Answer

$P\left( 9 \right)=89$

#### Work Step by Step

Substitute $x=9$, \begin{align} & P\left( 9 \right)=\frac{100\left( 9-1 \right)}{10} \\ & =89 \end{align} Thus, given a disease that smokers are 9 times more likely to die from than non-smokers, we see that 89% of deaths are related to smoking.
