To determine the sample space for the experiment of selecting a button from a bag containing a blue button (B), a red button (R), and a yellow button (Y) three times (with replacement), we need to consider all possible combinations of selections over the three draws.

Since there are 3 possible buttons for each draw and we are drawing 3 times, the sample space will consist of every possible combination of these buttons across the three draws. Each position in a selection can either be B, R, or Y.

The combinations can be represented in terms of sequences of three selections, such as:

  • BBB
  • BBR
  • BBY
  • BRB
  • BRR
  • BYB
  • BYR
  • BYY
  • RBB
  • RBR
  • RBY
  • RRB
  • RRY
  • RYY
  • YBB
  • YBR
  • YBY
  • YRB
  • YRR
  • YYY
  • YYY
  • YRY
  • ... and more.

Since there are 3 options (B, R, Y) for each of the 3 selections, the total number of combinations can be calculated as:

3 (choices for the 1st button) × 3 (choices for the 2nd button) × 3 (choices for the 3rd button) = 3^3 = 27 combinations.

Thus, the correct sample space consists of 27 possible combinations (sequences) such as:

  1. BBB
  2. BBR
  3. BBY
  4. BRB
  5. BRR
  6. BYB
  7. BYR
  8. BYY
  9. RBB
  10. RBR
  11. RBY
  12. RRB
  13. RRY
  14. RYY
  15. YBB
  16. YBR
  17. YBY
  18. YRB
  19. YRR
  20. YYY
  21. YRY
  22. YRB
  23. BRY
  24. BYX
  25. ...

So the sample space for this experiment is the set of all 27 possible outcomes with three button selections.

Looking at your provided options, none of them accurately represent the complete sample space as defined above. If you are supposed to identify a set that contains all these combinations, it looks like there is a typographical error since it is difficult to decipher the correct option under the provided texts.

The correct approach is to list from the theoretical outcome, which clearly states the defined sets of buttons in sequences of three.
