Find the probability of getting a sum of 7 and call that p(7). Now the complement rule says 1-p(7) is the probability of not getting 7.
The ways we get 7 are 1 and 6, or 2 and 5, or 3 and 4.
If you make a table with 1-6 on the top and 1-6 on the side, you can let each entry in your table be the sum of the top row and the side column. Since this is a 6x6 table, you can see
there are 36 outcomes.
6 of those outcome result in a sum of 7.
They are:
1+6
6+1
2+5
5+2
3+4
4+3
So p(7) =6/36 or 1/6. P of not getting 7 is 1-1/6=5/6

You roll two dice What is the probability of the event that you roll a total of seven or twelve on the two dice?
The probability is 7/36.
The probability of getting two 6s in a row when you roll a dice two times?
1 in 36
What is the probability of getting a 7 on one roll of a die?
The probability of getting a 7 on one roll of a die is zero.If you meant to ask about two dice, the probability is 6 in 36, or 1 in 6.
What is the probability of rolling both doubles and two odd numbers?
The answer depends on how many dice you roll and how often. If you roll four dice once, the probability of getting a double AND two odd numbers is 264/1296 = 11/54
What is the probability of rolling a 12 in a single roll of two dice?
The probability of rolling a sum of 12 in a single roll of two dice is 1 in 36, or about 0.0278.
What is the probability of getting a two on a single roll of dice?
1:6

What is the probability of getting a 7 on one roll of a die?
The probability of getting a 7 on one roll of a die is zero.If you meant to ask about two dice, the probability is 6 in 36, or 1 in 6.
What is the probability that if you roll the dice you'll get the number 100?
That depends on what kind of dice you are rolling and how many of them you roll. If you roll two 6-sided dice once, the probability of getting the number 100 is exactly zero. You cannot get a 100 on one roll of two 6-sided dice. Other dice and different numbers of them may yield different probabilities.
What is the probability of rolling both doubles and two odd numbers?
The answer depends on how many dice you roll and how often. If you roll four dice once, the probability of getting a double AND two odd numbers is 264/1296 = 11/54
What is the probability of rolling a 12 in a single roll of two dice?
The probability of rolling a sum of 12 in a single roll of two dice is 1 in 36, or about 0.0278.
If you roll two dice what is the probability of getting an odd number?
The probability of getting an odd number when you roll one die is 1 in 2. In order to get an odd sum with two dice, one of them has to be odd and one of them has to be even. The probability of rolling an odd sum is still 1 in 2, since each die is unrelated in probability to the other.
If 11 is the sum and you roll two dice what is the probability of getting 11 if you toss the dice 54 times?
The probability of getting 11 with one throw of 2 dice is 1/6*1/6*2 = 1/18 So the probability of not getting 11 with 1 throw of the dice is 17/18. Tossing the dice 54 times, the probability of not getting 11 54 times is (17/18)54 = 0.0456... So the probability of at least 1 roll of 11 is 1 - 0.0456 = 0.954
What is the probability if you roll 1 unfair dice 2 times of getting two fives where the probability of 5 is 0.3?
0.3 * 0.3 = 0.09
What is the probability of rolling the sum of two if you roll a pair of dice sixty times?
The probability of getting a sum of 2 at least once is 0.8155
What is the probability of a sumof 7 if you roll two dice?
The probability is 1/6.
