So the answers are included but I would like to see how the answer was worked out because in number 2 I didn't get 1/6. 10, 11, and 12 would be the higher then 9 and that's 4/36 (5&5,6&5,6&6, 5&6)Then in question 3 how did they get 2/24.I'm studying for my Midterm so if you can show me the work for these two please. Thanks
