Gloria has two number cubes with faces numbered 1 through 6. She will roll each number cube once.

Part A Make an organized list to show the sample space for rolling the two number cubes once.
(You can make a list or a tree diagram to represent the sample space.)

Part B How many possible outcomes are in the sample space for rolling the two number cubes once?

Part C Gloria wants to roll the number cubes once and get a sum of 8 on the top faces.
List the outcomes in the sample space that have a sum of 8.

Part D What is the probability that Gloria will get a sum of 8 on the top faces when she rolls the two number cubes once?

Answer 1

Explanation:

There are 36 possibilities. That's a lot. I'll give you the two sets of them to give you the idea of how to set it up.

1 1

1 2

1 3

1 4

1 5

1 6

Now you can list all the reverse numbers

2 1

3 1

4 1

5 1

6 1

Do this pairing all the way down and then add the doubles amount.

B: 36 (Stated Above)

C:

4 4

3 5

5 3

6 2

2 6

D

There are 36 possible outcomes.

The Probability is 5/36

The Probability is 0.1388 .... repeating.
