## What is the probability of getting a sum of 5 when rolling two dice?

1/9

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 4 when two dice are rolled?

1/12

Answer: The probability of rolling two dice and getting a sum of 4 is 1/12.

**What is the probability of getting a sum of 10 when two dice are rolled?**

(1) There are three ways for the sum of the dice to be 10: rolls of 4,6 and 5,5 and 6,4. (2) We can use conditional probability to confirm: Here we define P(A) as the probability of rolling a sum of 10, and P(B) as the probability that a die shows a 4. P(A and B) is the probability that the sum is 10 and there is a 4.

### What is the probability of getting a sum of 6 if two dice are thrown?

5/36

Answer: The probability of rolling a sum of 6 with two dice is 5/36.

### What is the probability of getting a sum of 4 in a toss of a pair of dice?

There are six faces for each of two dice, giving 36 possible outcomes. If the two dice are fair, each of 36 outcomes is equally likely. Three outcomes sum to 4: (1+3), (2+2) and (3+1). Probability of getting a sum of 4 on one toss of two dice is 3/36, or 1/12.

**What is the probability of getting a sum of 4 dice?**

Probabilities for the two dice

Total | Number of combinations | Probability |
---|---|---|

2 | 1 | 2.78% |

3 | 2 | 5.56% |

4 | 3 | 8.33% |

5 | 4 | 11.11% |

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

What is the probability that sum on both faces is 9 when two dice are thrown simultaneously? So, P(sum of 9) = 1/9.

#### What is the probability of 2 6?

2.78 percent

So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.

**How to calculate the probability of rolling a fair dice?**

To determine the probability of rolling any one of the numbers on the die, we divide the event frequency (1) by the size of the sample space (6), resulting in a probability of 1/6. Rolling two fair dice more than doubles the difficulty of calculating probabilities.

## How many possible outcomes are there when you roll two dice?

You will notice that in each row there is one dice roll where the sum of the two dice is equal to seven. Since there are six rows, there are six possible outcomes where the sum of the two dice is equal to seven. The number of total possible outcomes remains 36.

## What is the probability of rolling a die?

Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on. But what happens if we add another die?

**What’s the probability of getting any side of the die?**

Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6 and so on for 3, 4, 5, and 6.
