There are 21 different combinations of two dice. Three of them total 7 (3 + 4, 2 + 5, 1 + 6), so if you have two 'fair' dice, you have a 1 in 3 chance of totalling 7.
With one roll of three dice, the probability is 7/8.
In one roll the probability is 1/36.
there is a 1 to 5 probablilty that you will roll the sum of 6 with two dice.
The probability is 1 out of two. The primes you can roll are 2,3, and 5.
If you roll them often enough then the probability is 0. For just one roll, the probability is 35/36.
5/36
The probability of rolling a sum of 12 in a single roll of two dice is 1 in 36, or about 0.0278.
It is 5/6.
With one roll of three dice, the probability is 7/8.
The probability that you roll a 3 or a 5 on one or both dice is 20/36 = 5/9
1/12
That depends on whether you roll it twice or not...
It is 1 (a certainty) if you roll it often enough. For a single roll of a fair die, the probability is 1/6.
In one roll the probability is 1/36.
The probability of rolling a 1 on a die is 1/6 if you roll it once.
It is 1: if you roll the die often enough. On a single roll of a fair die, the probability is 1/6.
The probability of rolling either a 6 or 4 on one roll of a dice is two thirds (one sixth plus one sixth because both four and six have a probability of one sixth.
