Kai and Liam are on an adventure in the world of probability! They're flipping a magical coin and recording how many times it lands on heads and how many times it lands on tails.

Amidst their fun experiment, which statement about the experimental and theoretical probability holds true?

• The experimental probability should get closer to the theoretical probability as Kai and Liam conduct more experiments.

• The experimental probability should get further from the theoretical probability as Kai and Liam conduct more experiments.

• The experimental probability should stay the same distance from the theoretical probability as Kai and Liam conduct more experiments.

• The number of experiments Kai and Liam conduct will not affect the experimental probability.
