## What is the probability of getting a sum from two throws of a dice?

Aptitude :: Probability – Discussion

4. 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 of rolling 2 dice and getting a sum of 9?

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

## What is the probability of rolling two dice and getting a sum of 7?

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 getting 9 on two dice?

Probabilities for the two dice

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

6 | 5 | 13.89% |

7 | 6 | 16.67% |

8 | 5 | 13.89% |

9 | 4 |
11.11% |

## What is the probability of getting at least one?

To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1. That is, **P(at least one) = 1 – P(none)**.

## 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.

## What is the probability that the sum of two dice is 5?

The probability of rolling a pair of dice whose numbers add to 5 is 4/36 = **1/9**.

## When two dice are tossed asynchronously What is the probability of getting the sum of 6?

Therefore probability of getting sum 6= **5/36**.
