How does the experimental probability of an event change with more trials?

• It becomes less predictable

• It becomes more predictable

• It approaches the theoretical probability

• It does not change

What is the purpose of calculating relative frequency in experiments?

• To confirm the theoretical probability

• To make predictions about future events

• To prove the experimental probability wrong

• To change the outcome of the experiment

Why is it important to perform a large number of trials in an experiment involving probability?

• To increase the accuracy of the experimental results

• To ensure the experimental probability equals the theoretical probability

• To make the experiment more complex

• To reduce the cost of the experiment
