Question 200314: If I were to roll 2 six-sided dice, what is the probability that the sum of the 2 dice will be exactly 8? What is the probability that the sum will be 10 or more? Feel free to write out a table to help determine all possible conclusions. Could you please show me the steps on how to find this answer. Thank you.

With a pair of 6-sided dice, there are exactly 36 different results:
2: 1 + 1, exactly 1 way
3: 1 + 2, 2 + 1, exactly 2 ways
4: 1 + 3, 3 + 1, 2 + 2, exactly 3 ways
5: 1 + 4, 4 + 1, 2 + 3, 3 + 2, exactly 4 ways
6: exactly 5 ways
7: exactly 6 ways
8: exactly 5 ways
9: exactly 4 ways
10: exactly 3 ways
11: exactly 2 ways
12: exactly 1 way
and 
Probability of an 8: The number of ways to make an 8 divided by the total possible results, i.e. 
Probability of 10 or more: The number of ways to make a 10 plus the number of ways to make 11 plus the number of ways to make 12 all divided by the total possible results, i.e.
