                            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

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


(2)   If you agree with this re-formulation,  then here is the second part of my post,
        which is the solution and the answer to this re-formulated question:

         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.     ANSWER

Solved.
