What is the probability of getting a sum of 13 when 2 dice are rolled?
For a dice, the maximum number that it has is 6. Thus, obtaining the sum 13 is an unlikely event to happen in the throwing of the two dice. So, the probability of an unlikely event is zero. Here too, the probability is zero.
When two dice are rolled what is the probability of getting a sum of 12?
Probabilities for the two dice
| Total | Number of combinations | Probability |
|---|---|---|
| 9 | 4 | 11.11% |
| 10 | 3 | 8.33% |
| 11 | 2 | 5.56% |
| 12 | 1 | 2.78% |
What is the probability that the sum of the two numbers appearing on the top of the dice is 13?
If two dice are thrown simultaneously there is no outcome where the sum of the two numbers appearing on the top is 13. Hence the required probability is zero.
When 4 dice are thrown what is the probability of obtaining sum of 13?
Probability that the sum of the number appearing on them is 13, is. The total number of elementary events associated with the experiment of throwing four dice is 6×6×6×6=64.
When 4 dice are thrown what is the probability that the sum of the numbers appearing on the dice is 18?
What is the probability that the sum of the numbers appearing will be 18 if 4 dice are thrown? Probability=4/1296=1/324.
What is the probability that the sum of the numbers thrown will be 4?
Probability of getting a sum of 4 on one toss of two dice is 3/36, or 1/12.
When two dice are rolled what is the probability of getting a sum is either 7 or 11?
What is the probability of rolling a sum of 7 or 11 with two dice? So, P(sum of 7 or 11) = 2/9.
What is the probability that when two dice are rolled the sum of the numbers on the two dice is 7?
For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
