Note that there are 36 possibilities for (a,b). This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of joint outcomes (a,b) is 6 times 6 which is 36.

## What are the possible sums if you roll two dice?

So, **when we roll two dice** there are 6 × 6 = 36 possibilities.

## What is the probability of rolling a 2 on a 6 sided die?

Probability of rolling a certain number or less for two 6-sided dice.

…

Two (6-sided) dice roll probability table.

Roll a… | Probability |
---|---|

2 |
1/36 (2.778%) |

3 | 2/36 (5.556%) |

4 | 3/36 (8.333%) |

5 | 4/36 (11.111%) |

## When two sided dice are rolled There are 36 possible outcomes?

Every time you add an additional die, the number of possible outcomes is multiplied by 6: 2 dice 36, 3 dice 36*6 = **216 possible outcomes**.

## What is the chance of getting 7 or 11 with two dice?

What about 7 OR 11? There are 6 x 6 or 36 options, all are equally likely, 7 occurs 6 times, so the chances are 6/36 or 1/6. 11 occurs 2 times so chances are **2/36 or 1/18**. 7 or 11 are 8 of the 36 options so 8/36 or 2/9.

## How many unique combinations are there with 2 dice?

Note that there are **36 possibilities** for (a,b). This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of joint outcomes (a,b) is 6 times 6 which is 36.

## What is the probability of getting a 7 when rolling 2 dice?

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is **6/36 = 1/6**.

## What is the probability of rolling a 5 with two dice?

To find the probability determine the number of successful outcomes divided by the number of possible outcomes overall. Each dice has six combinations which are independent. Therefore the number of possible outcomes will be 6*6 = 36. The probability of rolling a pair of dice whose numbers add to 5 is **4/36 = 1/9**.

## What is the probability of getting a sum of 20 when tossing 2 dice?

Answer Expert Verified

The maximum sum that we can get when we roll 2 dice is 12. So, the probability of getting 20 is obviously .

## How many ways can a sum of 2 or a sum of 10 be rolled with a pair of dice?

If you consider the chart on the webpage given, there are **36** combination of rolls you can get from two dice. When you consider the sum being 10, there are only 3 combinations. So, the probability of getting a 10 would be 3/36 = 1/12.

## What is the probability of rolling a sum of 9 with two dice?

The probability of getting 9 as the sum when 2 dice are thrown is **1/9**.
