A) 2/3
B) 2/9
C) 1/3
D) 1/9
E) 1/10
Total number of outcomes possible when a die is rolled = 6   Hence n(S) = 6 * 6= 
<gadget id="calculator">6 * 6</gadget>
<output>36</output>
36   E= Getting a sum of 9 when the two dice fall = {(3,6),(4,5),(5,4),(6,3)}   hence n(E) = 4   =&gt;4/36 = 1/9   ANSWER 1/9
<result>D</result>
