The true statement about the experiment is:
The ratio \( \frac{92}{200} \) represents the number of occurrences of the coin landing heads up in this experiment.
To clarify the other options:
-
Experimental Probability: The ratio \( \frac{92}{200} \) does represent the experimental probability of landing heads up, as it is calculated by dividing the number of heads (92) by the total number of trials (200).
-
Number of Trials: The number of trials in the experiment is 200, not the ratio \( \frac{92}{200} \).
-
Theoretical Probability: The theoretical probability of landing heads up for a fair coin is \( \frac{1}{2} \) or 0.5, not based on Tia's experiment results. The ratio \( \frac{92}{200} \) is derived from the specific outcomes of the experiment.
Thus, while one of the statements is correct, it is important to note that the ratio also represents the experimental probability; however, the statement about representing the occurrences is more specifically correct.
