When the 𝟑𝟎 boxes of ornaments arrive, the art teacher counts the number of broken ornaments in each box. The table shows the results.
Which statement is true?
The number of boxes observed with 0 broken ornaments is greater than the number expected by the theoretical probability, so the theoretical probabilities must be inaccurate.
The number of boxes observed with 1 broken ornament is greater than the number expected by the theoretical probability, but the theoretical probabilities may still be accurate.
The number of boxes observed with 2 broken ornaments is less than the number expected by the theoretical probability, so the theoretical probabilities must be inaccurate.
The number of boxes observed with 3 broken ornaments is less than the number expected by the theoretical probability, but the theoretical probabilities may still be accurate.
