The sample space has 36 elements (the total number of outcomes by rolling the two dice).
There are 6 double outcomes: (1,1), (2,2), (3,3), (4,4), (5,5) and (6,6).
There are 5 outcomes whose sum is 6: (1,5), (5,1), (2,4), (4, 2), and (3,3).
The probability of rolling doubles OR the sum of 6 is 6/36 + 5/36 = 11/36.

If two fair dice are rolled what is the probability that the total number of spots shown is equal to 15?
If two fair dice were rolled, there would be 36 outcomes. (1,1),(1,2),....,(6,6) The maximum sum would be 12. Therefore, the probability that the total number of spots shown is equal to 15 is zero.
What is the probability of not rolling a number larger than 4 with a fair die?
The probability of not rolling a number larger than 4 is the probability of rolling a number equal to 4 or lower: P(x≤4) = P(1) + P(2) + P(3) + P(4) = 4/6 = 2/3 = 0.6666... ≈ 66.7%
What is the probability of rolling two numbers whose sum is 2 equal?
For 6 sided dice, there is only 1 way to get a 2: (1,1). There are 36 outcomes rolling 2 dice; so the probability of rolling two numbers whose sum is 2 is 1/36.
What is the probability of rolling an even number on an eight-sided die?
Assuming that there are an equal number of even and odd faces on the eight-sided die, then the probability of rolling an even number is simply 4 in 8, or 1 in 2, or 0.5.
If two fair dice are rolled what is the probability that the total number of spots shown is equal to 5?
Each of the dice has 6 sides. There are 6 x 6 = 36 possible combinations. Of those, the following equal 5: 1 and 4 2 and 3 3 and 2 4 and 1 So the odds of rolling a 5 is 4 chances out of 36 4 / 36 = 1 / 9 That converts to a probability of 0.1111111...
What is the probability of rolling a number less than or equal to 12 when rolling two number cubes?
It is 1.
What is the probability of rolling a 5 and then rolling a number greater than or equal to 2 on a regular six sided die?
the answer is 4
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.
Is it significant to get a twelve when a pair of dice is rolled with probability of less than or equal to five tenth?
The probability to get a 12, with two dice, is 1/36.
What is probability of rolling a number less than or equal to 2 on then number cube?
It is 1/3
What is the probability of getting a 5 on a single roll?
For a 6 sided die, each number 1 - 6 has equal probability. So, probability of rolling a 5 is 1/6.
If two twelve side fair dice are rolled what it the probability that the total number of spots shown is equal to 5?
If two twelve side fair dice are rolled, there are 144 possible outcomes. Of those 144 outcomes, there are four (1-4, 2-3, 3-2, and 4-1) that add up to five, So the probability of rolling a sum of five is 4 in 144, or 1 in 36.
What is the probability of rolling a number greater than or equal to 3?
The answer depends on what you are rolling: a number cube or some other shape? For a die, the answer is 2/3.
If two fair dice are rolled what is the probability that the total number of spots shown is equal to 15?
If two fair dice were rolled, there would be 36 outcomes. (1,1),(1,2),....,(6,6) The maximum sum would be 12. Therefore, the probability that the total number of spots shown is equal to 15 is zero.
What is the probability of rolling a seven in any combination on a pair of dice?
6/36 which is equal to 1/6
If a die is rolled what is the probability of getting a number less than or equal to 6?
Since all numbers on a die are 6 or below, the probability is 6/6, 1, or 100%.
What is the probability of not rolling a number larger than 4 with a fair die?
The probability of not rolling a number larger than 4 is the probability of rolling a number equal to 4 or lower: P(x≤4) = P(1) + P(2) + P(3) + P(4) = 4/6 = 2/3 = 0.6666... ≈ 66.7%
