<output>0.18</output>
0.18;   Brendon and Kane score less than or equal to 700, while Daniel scores more than 700= 0.6*0.4*0.5= 
<gadget id="calculator">0.6*0.4*0.5</gadget>
<output>0.12</output>
0.12;   Kane and Daniel score less than or equal to 700, while Brendon scores more than 700= 0.5*0.4*0.4 = 0.08.   The sum of the above = 0.5.   Answer: 0.5.
