3; 1 and 6, 2 and 5, 3 and 4.
With 2 6-sided dices there are 6x6=36 combinations (6 for the first dice, 6 for the second dice) Let put the question this other way: how many combinations with a total more than 8, namely 9, 10, 11 or 12 ? 9: 4 combinations: 4-5 or 5-4 or 6-3 or 3-6 10: 3 combination: 5-5 or 6-4 or 4-6 11: 2 combinations: 6-5 or 5-6 12: 1 combination: 6-6 So there are 10 combinations for "more than 9" thus there are 36-10=26 combinations for "less or equal to 8".
There are 18 permutations or 5 combinations. And it is one die, many dice. There is no such word as dices or diceses.

7*3*4 = 84 combinations.
Since there are 6 sides on each die, and you have 3 dice, you do 6x6x6. Which is 216 combinations.
3; 1 and 6, 2 and 5, 3 and 4.
There are 21 different combinations of two dice. Three of them total 7 (3 + 4, 2 + 5, 1 + 6), so if you have two 'fair' dice, you have a 1 in 3 chance of totalling 7.
6 different combinations can be made with 3 items
With 2 6-sided dices there are 6x6=36 combinations (6 for the first dice, 6 for the second dice) Let put the question this other way: how many combinations with a total more than 8, namely 9, 10, 11 or 12 ? 9: 4 combinations: 4-5 or 5-4 or 6-3 or 3-6 10: 3 combination: 5-5 or 6-4 or 4-6 11: 2 combinations: 6-5 or 5-6 12: 1 combination: 6-6 So there are 10 combinations for "more than 9" thus there are 36-10=26 combinations for "less or equal to 8".
216/3 = 72
There are 18 permutations or 5 combinations. And it is one die, many dice. There is no such word as dices or diceses.

7*3*4 = 84 combinations.
Assuming of course that we are talking about cubic dice. combinations that make 9: 6&3, 5&4, 4&5, 3&6. There are 4 combinations that make 9. There are 36 possible combination of two dice. So 4/36 is 1/9

Fair dice are dice that are not weighted on one side to make a particular number more probable than the others. The probablity of a four on one dice is 1/6. The probability of a four showing on either or both of two dice is 1/6 + 1/6 = 1/3 (Note this is different from rolling a total score of four with two dice which can be achieved with 1+3, 3+1 or 2+2 which is 3 out of 36 combinations or 3/36)
