The probability of spinning and landing on red is 20%. Meg spins the spinner 25 times and lands on red 10 times, or 40% of the time. She spins the spinner 80 times and lands on red 18 times or 22.5% of the time. What is a good explanation for this?

A) Meg miscounted the first time.

B) The spinner broke the second time and didn't land on red.

C) The less trials you do, the closer experimental probability gets to the theoretical probability.

D) The more trials you do, the closer experimental probability gets to the theoretical probability.

D is your correct answer, the more trials you do, the closer you get to an accurate probability. Think of it like scientific trials. The less you do, the further you are from creating an accurate law of science, but something that has been tested over and over again is more likely to be accepted as an accurate fact.
