Your question: When two dice are rolled find the probability of getting a sum of 7 or 8?

What is the probability of rolling 2 dice and getting a sum of 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.

What is the probability of getting a sum of 8 when two dice are thrown?

So the probability is the sum of the five individual probabilities which is 5*(1/36)= 5/36. Therefore the probability that we get the sum as 8 when two dice are thrown is 5/36.

What pair has a sum of 7?

Therefore, 2 and 5 is a pair of integer whose sum is 7.

What is the probability that you obtain a sum of 7 or a sum of 11 on the first roll?

For example, since a 7 or an 11 is a winner on the first roll and their probabilities are 6/36 and 2/36, the probability of winning on the first roll is 6/36+2/36=8/36.

What is the probability of rolling a sum of 8 on a standard pair of six sided dice?

Two (6-sided) dice roll probability table

Roll a… Probability
6 5/36 (13.889%)
7 6/36 (16.667%)
8 5/36 (13.889%)
9 4/36 (11.111%)

What is the probability of not getting a sum of 8 if a pair of dice is rolled?

The probability of any number occurring is 1 in 36 or 1 / 36. Then the probability an 8 will not occur is: 1 – 5 / 36 or 31 / 36.
