When two dice are thrown find the probability of getting sum more than 9?

So probability of getting a sum greater than 9 is= 6/36=1/6 Ans.

What is the probability of getting a sum 9 from two throws of a?

4. What is the probability of getting a sum 9 from two throws of a dice? Explanation: In two throws of a dice, n(S) = (6 x 6) = 36.

What is the probability of rolling two dice to obtain the sum 9 or the number 4 on at least one die?

So, there are only 2 combos that sum to 9 and have at least 1 of the die be a 4. So the probability is: (number of combos we want)/(total number of combos) = 2/36. Reduced, this is 1/18.

How many outcomes have a sum of at least 9?

(ii) two numbers appearing on them whose sum is 9. Therefore, total number of possible outcomes = 36.

How many ways can you get a sum of 9?

So in total there are 25 ways to get a sum of 9. If you want the probability, just take this over the total number of possibilities and you get 25/63=25/216.

What is the probability of rolling 9 or greater?

What is the probability of getting the sum as 9 when three dice are thrown?

Probability of a sum of 9: 25/216 = 11.6%

What is the probability of getting a sum of 7 from two throws of a dice?

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.
