Prob(Not 7) = 1 - Prob(7) = 1 - 6/36 = 1- 1/6 = 5/6

Suppose you roll tow dice Find the probability of rolling a sum of 8?
5/36
Find the odds of rolling less than a four by rolling the dice once?
The probability is 3/6 or 1/2
Find the probability of rolling a sum of 5 with 2 dice?
The probability of rolling a sum of 5 with two die is 4 over 36, or 2 over 18, or 1 over 9.
Suppose you roll two number cubes once Use the counting principle to find the probability of rolling a 4 on both cubes?
The probability of rolling 4 and 4 on a single roll of two dice is 1 in 36. You don't have to count. The probability of rolling 4 on one die is 1 in 6. The probability of rolling two 4's is (1 in 6) squared or 1 in 36. If you insist on counting, go ahead, 11, 12, 13, 14, 15, 16, 21, 22, 23, 24, etc. You will find 36 combinations, with only one 44 in them, hence 1 in 36.
When two dice are rolled find the probability of not rolling a sum of 5?
When rolling a pair of dice there are 6∙6 = 36 possible outcomes. The outcomes that give a sum of 5 are 4, [(1,4), (2,3), (3,2), (4,1)]. So the probability of not rolling a sum of 5 is: P(NOT 5) = 1 - P(5) = 1 - 4/36 = 32/36 = 8/9 = 0.8888... ≈ 88.9%

What is the probability of rolling a 7 or 11 with two dice?
The probability of rolling a 7 with 2 dice is 6/36; probability of rolling an 11 is 2/36. Add the two together to find probability of rolling a 7 or 11 which is 8/36 or 2/9.
Find the probability of rolling a sum of 12 with two dice?
It is 1/36.
Find the probability of rolling a sum of 9 with two dice?
There is 4 ways to roll a 9 with 2 dice, and 36 possible outcomes. So, the probability of rolling a sum of 9 with two dice is 4/36 or 1/9.
A pair of dice are rolled find the probability at least one dice is a 4?
When rolling one die, the probability of getting a 4 is 1 in 6, or 0.1667. If two dice are rolled, you get two unrelated chances of rolling at least one 4, so the probability is 2 in 6, or 0.3333.
Find the odds of rolling less than a four by rolling the dice once?
The probability is 3/6 or 1/2
Find the probability of rolling a sum of 5 with two dice?
The probability of rolling a sum of 5 with two dice is 4 in 36, or 1 in 9, or about 0.1111. 1 and 4 2 and 3 3 and 2 4 and 1
Find the probability of rolling a sum of 8 with two dice?
The probability of rolling a sum of 8 with two dice is 5 in 36 or about 0.1389. 2 and 6 3 and 5 4 and 4 5 and 3 6 and 2

Find the probability of rolling a sum of 5 with 2 dice?
The probability of rolling a sum of 5 with two die is 4 over 36, or 2 over 18, or 1 over 9.
When two dice are rolled find the probability of getting a sum of 5 or 6?
There are 36 permutations of two dice. Of these, 9 have a sum of 5 or 6, so the probability of rolling a sum of 5 or 6 on two dice is 9 in 36, or 1 in 9, or about 0.1111.
