What is the probability of rolling 7 or 11 with 2 dice?
The probability of rolling a 7 on a pair of 2 dices is: P(7) = 6/36.The probability of rolling a 11 on a pair of 2 dices is: P(11) = 2/36.The probability of rolling 7 or 11 is the sum of both single probabilities:P(7 or 11) = 6/36 + 2/36 = 8/36 = 2/9 = 0.2222... ≈ 22.2%.Explanation.When rolling a pair of fair dice there are 36 possible equiprobable events oroutcomes. They are:(1,1), (1,2), (1,3), (1,4), (1,5), (1,6),(2,1), (2,2), (2,3), (2,4), (2,5), (2,6),(3,1), . . . . . . . . . . . . . . . . . , (3,6),(4,1), . . . . . . . . . . . . . . . . . , (4,6),(5,1), . . . . . . . . . . . . . . . . . , (5,6),(6,1), . . . . . . . . . . . . . . . . . , (6,6).Each of these 36 events has the probability of happening of 1/36.For the case of the sum of both dice to be 7, there are 6 possible outcomes, so theprobability of the event sum equals 7 is: P(7) = 6/36 = 1/6.For the case of the sum of both dice to be 11, there are 2 possible outcomes, (6,5)and (5,6), so the probability of the event sum equals 11 is: P(11) = 2/36 = 1/18.
What is the probability of rolling a sum of 10 or a sum that is an odd number when two number cubes are rolled?
The probability is 21/36 = 7/12
If 2 dice are rolled what is the probability of rolling a sum less than 7?
It is 15/36.
When rolling a pair of dice determine the probability of rolling a number less than 7?
5 over 11
What is the probability of getting a sum of 7 or 11 by rolling two dice if the first roll is a 3?
If the first roll is a three, it's impossible to get an eleven (the highest you can get is a 9), so the probability is 0. The way to get a sum of 7 is to add 3 and 4. The probability of getting a 4 on the second die is 1/6. Therefore, by adding the two probabilities of the outcomes (0 and 1/6), you get the answer: 1/6.
What is the probability of rolling a sum of 11 with 2 dice?

The probability is 1/6.
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.

What is the probability of rolling a sum of 7 or a sum of 11?
If two fair number cubes are rolled, the answers are: Prob(7) = 6/36 = 1/6 Prob(11) = 2/36 = 1/18.
What is the probability of rolling a sum of 10 or a sum that is an odd number when two number cubes are rolled?
The probability is 21/36 = 7/12
What is the probability of rolling a sum of 7 with 2 dice?
Te probability of rolling a sum of 7 with two fair dice is 6 in 36, or 1 in 6, or about 0.1667.Of all the possible combinations of two dice, the sum of 7 has the highest probability, with the other combinations decreasing down to 2 and 12, with probabilities of 1 in 36, or about 0.0278.
What is the probability of getting a sum of 7 or 11 by rolling two dice?
There are 36 permutations of two dice. Of them, 6 have a sum of 7, (1+6, 2+5, 3+4, 4+3, 5+2, and 6+1) and 2 have a sum of 11 (5+6 and 6+5). The probability, then of getting a sum of 7 or 11 is (6 plus 2) in 36, or 8 in 36, or 2 in 9, or about 0.2222.
What is the probability to roll a sum of 7 with three die?
There are 216 permutations of three dice. Of these, 15 sum to 7.
