Question

If you roll two fair six-sided dice, what is the probability that the sum is 9 or higher?

Answer 1

Answer:

The probability of rolling a 9 or higher is is 10/36. You can simplify this this fraction to 5/18.

Step-by-step explanation:

Answer 2

By taking the quotient between the number of combinations that add to 9 or more and the total number of combinations, we will see that the probability is P = 0.278

How to find a probability?

Here we will assume that all the possible outcomes have the exact same probability.

Then the probability of getting 9 or higher is given by the quotient between the number of combinations that add to 9 or higher and the total number of combinations.

We have two dice with 6 outcomes each, so the total number of outcomes is 6*6 = 36.

Now let's count the number of combinations that add to 9 or more, these are:

dice 1   dice 2   sum

6            3           9

6             4            10

6             5            11

6             6             12

5             6             11

5             5             10

5              4             9

4              5             9

4              6             10

3               6             9

Counting these we have 10 combinations that add to 9 or higher, then the probability will be:

P = 10/36 = 0.278
