To find the sample space for choosing 2 marbles from the bag with replacement, we'll consider that since it's with replacement, each choice is independent, and each marble can be picked again after being selected.

The marbles are:

  • Yellow (Y)
  • Red (R)
  • Clear (C)
  • Green (G)
  • Blue (B)

When we draw two marbles with replacement, the sample space will consist of all possible ordered pairs of these marbles. This means for each first marble that we draw, we can draw any of the five marbles again for the second pick.

The possible combinations would look like this:

  1. (Y, Y)

  2. (Y, R)

  3. (Y, C)

  4. (Y, G)

  5. (Y, B)

  6. (R, Y)

  7. (R, R)

  8. (R, C)

  9. (R, G)

  10. (R, B)

  11. (C, Y)

  12. (C, R)

  13. (C, C)

  14. (C, G)

  15. (C, B)

  16. (G, Y)

  17. (G, R)

  18. (G, C)

  19. (G, G)

  20. (G, B)

  21. (B, Y)

  22. (B, R)

  23. (B, C)

  24. (B, G)

  25. (B, B)

So, the total sample space consists of 25 outcomes.

Looking at your options, none appear to match the correct format of showing the sample space. The correct way of organizing it would generally be tabular like:

| | Y | R | C | G | B | |---|---------|---------|---------|---------|---------| | Y | Y,Y | Y,R | Y,C | Y,G | Y,B | | R | R,Y | R,R | R,C | R,G | R,B | | C | C,Y | C,R | C,C | C,G | C,B | | G | G,Y | G,R | G,C | G,G | G,B | | B | B,Y | B,R | B,C | B,G | B,B |

If you can provide the tables again so I can specifically identify the correct one based on the format above, I'd be happy to help further!
