## What is the probability of getting a number 9 in a throw of dice?

Aptitude :: Probability – Discussion

What is the probability of getting a sum 9 from two throws of a dice? Explanation: In two throws of a dice, n(S) = (6 x 6) = **36**.

## What is the probability that the sum of 9 appears in a single throw of a pair of dice?

Probabilities for the two dice

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

7 | 6 | 16.67% |

8 | 5 | 13.89% |

9 | 4 |
11.11% |

10 | 3 | 8.33% |

## What is the probability of getting 9 or 10 on a single throw of dice?

Total number of outcomes we get in a single throw of two dice = 6 × 6 6times 6 6×6 = 36. So, total of 4 cases. So, total of 3 cases. Expected number of outcomes = Total possible cases of getting ‘nine’ or ‘ten’ in a single throw of two dice = **4 + 3 = 7** .

## What is the probability of getting a score of 9 when a regular die is rolled twice?

The probability is **19** . See explanation.

## 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 is the probability of getting a doublet when two dice are thrown?

Probability of getting a doublet = 6/36 = **1/6**.

## What is the probability of getting a doublet of even number?

We know that the favourable outcomes are (2, 2), (4, 4), and (6, 6). So, the number of favourable outcomes is 3. We know that the number of possible outcomes is 36. Thus, the probability of getting a doublet of an even number is =**336=112**.

## What is the probability of getting a total of 9 or 11?

P(of getting a total of 9 or 11) = **1 / 6**.

## When two dice are thrown the sum obtained is 10?

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 getting a 10 in a single dice?
