In this experiment, we are selecting a coin (either a nickel (N) or a quarter (Q)) from a bag two times, with replacement. This means that after each selection, the chosen coin is put back into the bag before the next selection.

Each selection has two possible outcomes: either N (nickel) or Q (quarter). Therefore, when we perform this experiment twice, we can list all possible outcomes:

  1. Select N first, then N second: NN
  2. Select N first, then Q second: NQ
  3. Select Q first, then N second: QN
  4. Select Q first, then Q second: QQ

Thus, the complete sample space for the experiment is:

\[ { NN, NQ, QN, QQ } \]

The correct response is:

NN, NQ, QN, QQ
