# What is the theoretical probability of rolling sum of 7?

## Answer

###### Wiki User

###### 01/12/2013

-- 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 ... 6
- 2 ... 5
- 3 ... 4
- 4 ... 3
- 5 ... 2
- 6 ... 1

-- So the probability is 6/36 = 1/6 = 162/3 % .

-- The probability is the probability, not the 'theoretical' probability.

### 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... ≈

### How do you work out the probability of dice problems?

Count the number of permutations of the expected results and
divide by the number of permutations of the possible results.
This is standard probability theory, and it applies to
everything in probability, not just dice.
For instance, with two dice, there are 36 possible permutations,
while there is only 1 permutation that adds up to a sum of 2,
though there are 6 permutations that add up to a sum of 7. As a
result, the probability of rolling a sum of...

### What operation is used when calculating the probability that 2 events will happen and Find the theoretical probability of rolling a total of 7 as a sum of two dices?

If the two events are unrelated, as they are in rolling two dice
or one die twice, simply multiply the probabilities together.
However, you also have to consider the permutations involved in
rolling dice and realize that there is more than one way to roll a
particular sum.
There are 36 permutations of rolling two dice. Of these, exactly
one has a sum of two, the the probability of rolling a sum of two
is 1 in 36, or about 0.02778. You...
