I'll help you solve the second question! If you see, they ask how many are greater than 7. Let's see, 6,2 5,3 4,4 3,5 2,6 6,3 5,4 4,5 3,6 6,4 5,5 4,6 5,6 6,5 6,6 And that is 15 possibilities out of a total 36. So Probability = \(\frac{Possible Outcomes}{Total Outcomes} = \frac{15}{36} = \frac{5}{12}\) Now I guess you can do the first and the third one similarly! Got it? :D
