## What is the probability of rolling at least a 4 on a die?

Two (6-sided) dice roll probability table

Roll a… | Probability |
---|---|

2 | 1/36 (2.778%) |

3 | 3/36 (8.333%) |

4 | 6/36 (16.667%) |

5 | 10/36 (27.778%) |

## What is the probability that at least one die shows a 4?

P(B) = 6 36 . Now, if the first die shows 4 there is only one way to make the sum of both dice equal 7 which means P(A ∩ B) = 1 36 . Therefore, the probability that the first die shows 4 given that the sum is 7 is P(A|B) = P(A ∩ B) P(B) = **1/36 6/36** = 1 6 .

## What is the probability that at least one of the three dice is a 4?

Outcomes containing at least one occurrence of 4 when rolling 3 dice: Therefore, **91** of the 216 possible 3 dice roll outcomes contain at least one (4).

## What is the probability of getting at least one 4 in a roll of two dice?

= 1/36 for showing at least a 4 in two dice. Therefore, the probability of tossing two dice and showing at least one 4 is **11/36**.

## What is the probability of getting at least one 6?

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. The probability of rolling at least one six is therefore **1 − 625/1296 = 671/1296 ≈** .

## How do you find the probability of at least?

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 probability that at least one die is a 3?

In 25/36 rolls there are no threes. Therefore in 11/36 rolls, or **31%**, will be at least one three.

## What is the probability of having at least one six from 3 throws of a perfect die?

Question: What is the probability of getting at least one six in a single throw of three unbiased dice? Answer: The probability of getting either 1 or 2 or 3 or 4 or 5 when one dice is thrown is 5/6 x 5/6 x 5/6 for 3 dices = **125/216**. This is the probability of getting at lease one 6 when 3 dices are thrown.

## What is the probability of throwing 6 with a dice at least once in 3 attempts?

Therefore the answer is **91/216**. Hope this helps!
