Which list gives the sample space for pulling 2 marbles from the bag with replacement?
List 1
List 2
List 3
List 4

Answer 1

When pulling 2 marbles from a bag with replacement, each draw is independent, meaning that the same marble can be drawn more than once. Therefore, we need to consider all possible combinations of 2 marbles, with replacement.

The marbles in the bag are:
- Orange (O)
- Green (G)
- Blue (B)

The possible combinations when pulling 2 marbles with replacement are:
1. O, O
2. O, G
3. O, B
4. G, O
5. G, G
6. G, B
7. B, O
8. B, G
9. B, B

Now, let's check which list matches these combinations:

- List 1 gives: O, O; O, G; O, B; G, O; G, B; G, G; B, B; B, G; B, O; G, O, O
- List 2 gives: O, O; O, G; O, B; G, O; G, B; G, G; B, B; B, G; B, O
- List 3 gives: O, O; O, G; O, B; G, O; G, B; G, G; B, B; B, G; B, O
- List 4 only gives a limited selection of combinations.

Based on the combinations listed, List 2 accurately reflects the complete sample space for pulling 2 marbles from the bag with replacement.

Thus, the answer is **List 2**.
