## What is the probability that 2 dice show the same number?

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).

## When two dice are rolled simultaneously What is the probability of getting the same number on each of them?

Total number of all possible outcomes = 36. (1,1),(2,2),(3,3),(4,4),(5,5),(6,6). Their number is 6. ∴ P(getting the same number on both dice) =**636=16**.

## What is the probability of rolling two dice with 2 as the outcome on both the dice?

If the die is fair (and we will assume that all of them are), then each of these outcomes is equally likely. 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.

## What is the probability of rolling two even numbers?

P(E)=636=16. Probability of two different even numbers = Probability of both even * Probability of both different given they are both even. Probability of both even is **12×12=14**.

## What is the probability of getting a prime number from 1 to 100?

The prime numbers from 1 to 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. Hence, the probability of the event that a number chosen from 1 to 100 is a prime number . Therefore, the correct option is (C).

## What’s the probability of rolling a 4?

Two (6-sided) dice roll probability table

Roll a… | Probability |
---|---|

4 | 3/36 (8.333%) |

5 | 4/36 (11.111%) |

6 | 5/36 (13.889%) |

7 | 6/36 (16.667%) |

## When two dice are thrown the total outcomes are?

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 rolling 2 standard dice which sum to 9?

When 2 dice are thrown, the probability of the sum being 9 is **1/9**.
