What is the probability of getting a 6 in a throw of a dice?
Two (6-sided) dice roll probability table
Roll a… | Probability |
---|---|
3 | 3/36 (8.333%) |
4 | 6/36 (16.667%) |
5 | 10/36 (27.778%) |

What is the probability of throwing a 6 or a 2 on a dice?
So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.
What is the probability of not rolling any 6’s in four rolls of a balanced die?
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.
How do you get 6 on a dice?
If you want to roll the 1 or 6, simply cover the numbers that are on opposite sides and bowl away. However, be wary that there is always a chance the dice will land on its side, especially if you’re not accustomed to this rolling technique.

What is the probability of rolling a sum of 3?
We divide the total number of ways to obtain each sum by the total number of outcomes in the sample space, or 216. The results are: Probability of a sum of 3: 1/216 = 0.5% Probability of a sum of 4: 3/216 = 1.4%
