<pre>

<U>ANSWER</U>.  P = {{{(0.05*0.05)/(0.05*0.05 + 0.95*0.005)}}} = 0.3448 = 34.48%

<U>Solution</U>


<pre>
They want you find the conditional probability  P(dies AND smoker | dies).


By the definition (and according to the common sense) 


    P(dies AND smoker | dies) = {{{P(dies_AND_smoker) / P(dies)}}} = {{{(0.05*0.05)/(0.05*0.05 + 0.95*0.005)}}} = 0.3448 = 34.48%    <U>ANSWER</U>

Solved.
