To quote one of our very good math and science tutors: “You will find here at Jiskha that long series of questions, posted with no evidence of effort or thought by the person posting, will not be answered. We will gladly respond to your future questions in which your thoughts are included.”
A. How many different ways can you get 7 with two dice?
6,1
1,6
5,2
2,5
3,4
4,3
Divide that by the total number of possible alternatives.
B. What odd numbers that can be obtained are greater than 6? (7, 9, 11) How many ways can they be obtained? Divide that by the total number of possible alternatives.
C and D have the same answer.
E. How many ways can you obtain "snake eyes"?Divide that by the total number of possible alternatives.
