When two dice are rolled the probability of getting a sum of 8 is?

What is the probability that the sum is 8 when throwing a dice given that the first die shows a 3?

The total number of ways to roll an 8 with 3 dice is therefore 21, and the probability of rolling an 8 is 21/216, which is less than 5/36. heads out of 20 is (20 10 ) /220 ≈ 17.6%.

What is the probability that the sum of the dice is 8 or 9?

Similarly, there are five possible combinations that give a sum of 8, so P(sum = 8) = 5/36. Four combinations give a sum of 9, so P(sum = 9) = 4 / 36 = 1/9.

When two dice are rolled what is the probability of 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.
