The probability that the sum of two dice is 7 is 6 in 36, or 1 in 6.

Of all the combinations, this is the one with the highest probability.

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 to obtain in sum the numbers 7 and 13 by throwing 3 dice?

Probability(Total = 7) = 15/216 = 0.069 Probability(Total = 13) = 21/216 = 0.097


What is the theoretical probability of rolling sum of 7?

-- There are (6 x 6) = 36 possible rolls for a fair pair of 6-sided dice.-- There are 6 ways to roll a sum of 7 :1 ... 62 ... 53 ... 44 ... 35 ... 26 ... 1-- So the probability is 6/36 = 1/6 = 162/3 % .-- The probability is the probability, not the 'theoretical' probability.


Probability of two tetrahedral dice rolled the sum on the upward faces is four?

When a tetrahedral die is rolled, it will rest with three faces upwards. If the die is numberd from 1 to 4. therefore the sum of the upward facing numbers on 1 die is at least 6 and so for two dice, the minimum is 12. That being the case, the probability is 0.


What is the probability that the sum of the numbers from two rolled dice result in a perfect square or even number?

Part1: Finding probability of getting sum as a perfect square. Maximum sum of both the dice is (6+6) equal to 12. Up to 12, the perfect squares are: 1, 4 and 9. Getting a sum of 1 from two dice is not possible. So, we are left with 4 and 9. To get 4, the combination can be: (2,2) or (1,3) or (3,1). This means, to get the sum as 4, the probability is [3/36]. To get 9, the combination can be: (3,6) or (6,3) or (5,4) or (4,5). This means, to get the sum as 9, the probability is [4/36]. Therefore,the total probability of getting the sum as a perfect square is: [(3/36)+(4/36)]=[7/36]. Part2: Finding the probability of getting sum as an even number. The possible even numbers can be 2, 4, 6, 8, 10 and 12. But, as 4 is already considered in part1, it should be ignored in this case. The probability of getting sum as 2 is: [1/36] The probability of getting sum as 6 is: [5/36] The probability of getting sum as 8 is: [5/36] The probability of getting sum as 10 is: [3/36] By adding all the above, the probability of getting sum as an even number (ignoring 4) is: [(1/36)+(5/36)+(5/36)+(3/36)]=[14/36]. From part 1 and part 2, we get the total probability as [(7/36)+(14/36)]=[7/12]=0.583333.

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. Therefore, the probability of rolling a sum of 7 with three dice is 15 in 216, or 5 in 72, or about 0.06944.111112113114115711612112212312471251261311321337134135136141142714314414514615171521531541551561611621631641651662112122132147215216221222223722422522623123272332342352362417242243244245246251252253254255256261262263264265266311312313731431531632132273233243253263317332333334335336341342343344345346351352353354355356361362363364365366411412741341441541642174224234244254264314324334344354364414424434444454464514524534544554564614624634644654665117512513514515516521522523524525526531532533534535536541542543544545546551552553554555556561562563564565566611612613614615616621622623624625626631632633634635636641642643644645646651652653654655656661662663664665666

If you roll a fair six-sided die and a fair four-sided die what is the probability that the dice add to 7?

It depends upon what numbers are on the faces of the dice. Assuming a standard die with faces 1-6 and the four sided die has faces 1-4, then: To get a sum of seven will require: 6-1, 5-2, 4-3 or 3-4 There are 4 successful rolls. There are 6×4 = 24 possible rolls → Probability(sum of 7) = 4/24 = 1/6

What is probability of rolling a sum of 3 with a pair of unfair dice with probability of 1 and 2 at 18 and the rest at 16?

The probability of any event MUST be a number between 0 and 1. It is not possible to have a probability of 18 or 16. Furthermore, given that the dice are not normal, the question should also specify how many faces they have and what numbers are on these faces.
