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%

When two dice are rolled find the probability of getting a sum less than 13?
Assuming these are regular dice, the probability is 1.
When 2 dice are rolled find the probability of getting a sum of 10 or doubles?
The probability is 8/36 or 2/9
When two dice are rolled find the probability that the sum is a multiple of 3 or greater than 4?
The probability is 35/36.
Two dice are rolled find the probability that the sum of observed values is equal to 13?
If two dice are rolled, the probability that the sum of observed values is equal to 13 is zero. The sum of two dice can only lie between 2 and 12, inclusive.
Find the odds of rolling less than a four by rolling the dice once?
The probability is 3/6 or 1/2
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 probability of rolling a 10 with two dice?
Assuming that the random variable is the sum of the two numbers rolled, the answer is 3/36 or 1/12.
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.
When two dice are rolled find the probability of getting a sum less than 13?
Assuming these are regular dice, the probability is 1.
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 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.
Find the odds of rolling less than a four by rolling the dice once?
The probability is 3/6 or 1/2
