## When rolling a number cube What is the probability of rolling a 2 or a 3?

Probability of rolling more than a certain number (e.g. roll more than a 5).

Roll more than a… | Probability |
---|---|

1 | 5/6(83.33%) |

2 | 4/6 (66.67%) |

3 | 3/6 (50%) |

4 | 4/6 (66.667%) |

### What is a rolling number cube?

Rolling A Number Cube. Students investigate the outcome of a random process by rolling a number cube 60 times and analyzing the results. By pooling their data with other groups, students are able to see that large numbers of events produce results that are closer to the predicted results.

#### What is the probability of not rolling a 3 on a die?

5/6

If we know that P(die = three) = 1/6,then we can say that P(not rolling a three) = 5/6.

**What is the probability of rolling an 1 or 2 on a number cube dice two times in a row?**

8 Answers. The probability of rolling a specific number twice in a row is indeed 1/36, because you have a 1/6 chance of getting that number on each of two rolls (1/6 x 1/6). The probability of rolling any number twice in a row is 1/6, because there are six ways to roll a specific number twice in a row (6 x 1/36).

**What is the probability of rolling an odd number?**

The probability when rolling a regular six-sided dice that the score is an odd number is three-sixths or three out of six.

## What is the probability of rolling a 3 on a number cube?

1/6

3 Answers By Expert Tutors A number cube is a 6 sided die, so the probability of rolling a 3 is 1/6.

### What is the probability of rolling a 7 on a number cube?

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 cube and having it land as a six?

16

Explanation: A number cube (dice) has six sides labelled 1 through 6. Hence, a fair dice has a probability of 16 to land on any predetermined number 1 through 6.

**What is the probability of not rolling any 6’s in four rolls of a balanced die?**

1) If we roll four dice, what is the probability of at least one six? a) Consider the complement problem, there is a 5/6 probability of not rolling a six for any given die, and since the four dice are independent, the probability of not rolling a six is (5/6)4 = 54/64 = 625/1296.

**What is the probability of rolling a 4 twice?**

The probability of rolling a specific number twice in a row is indeed 1/36, because you have a 1/6 chance of getting that number on each of two rolls (1/6 x 1/6).

## What is the probability of rolling a 4 twice in a row?

1/36

To compute the joint probability of an event, multiply the probability of each of the two events. For example, the chances of rolling a 4 with a single dice are 1/6, or 16.7%. The chances of rolling a 4 two times in a row are: 1/6 x 1/6 = 1/36 (2.78%).

### What is the formula of probability?

P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space….Basic Probability Formulas.
