Answer:
The greater the sample size, the closer the percentage.
Step-by-step explanation:
<u>Relative frequency</u>
The relative frequency of an event is the division of the number of times that an event occurs during experimental trials by the total number of trials conducted.
The percentage of the relative frequency of getting Head is usually very close to the theoretical probability of getting a Head. However, results vary for each experiment.
The sample size in this case is the number of experiments carried out. The greater the sample size, the closer the percentage of Heads will be to the theoretical probability of getting a Head.
