six possibilities

Probability of getting a number <7 is 66=1.

doublet refers to situation when two dices are thrown at once and both of them ends up getting same digits for ex. – 2and 2, 3and3 etc. This conversation is already closed by Expert.

As the chart shows the closer the total is to 7 the greater is the probability of it being thrown….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% |

We know that the total number of possible outcomes when two dice are thrown is =6×6=36. We know that the probability of any event is the ratio of the number of favourable outcomes and the number of possible outcomes.

The second roll of the dice has to match the outcome of the first, so that has a probability of 1/6. The probability of both events occurring is 1 * 1/6.

When two dice are thrown, the total number of sample spaces is 36. Hence, the probability of getting a sum of prime numbers = 15/36 = 5/12.

1 Expert Answer If you roll a single die there are 6 possible outcomes (1,2,3,4,5,6), 2 of which are greater than 4. So in a single roll the probability of getting a number greater than 4 is 2/6 = 1/3.
