Question 1199104
.



                            My response consists of two parts.



(1)   First part is to say that the problem is worded / posed / formulated  INCORRECTLY.



**********************************************************************


                    Because one client may have more than one car,

            and we even don't know,  how many cars an average client does have.


**********************************************************************



The correct question,  instead of  (a),  should be 


<pre>
    a) What is the expected mean annual payment to a client per each one single care ? 
</pre>


(2) &nbsp;&nbsp;If you agree with this re-formulation, &nbsp;then here is the second part of my post, 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;which is the solution and the answer to this re-formulated question:


<pre>
         Expected  mean annual payment to a client per each one single care is

             E = 0.02*15000 + 0.05*8000 + 0.1*5000 = 1200 dollars.     <U>ANSWER</U>
</pre>

Solved.
