Question

jamie rolls a 6-sided die 30 times and determines that the experimental probability of rolling a 2 is (\frac{1}{15}). the theoretical probability of rolling a 2 is (\frac{1}{6}). what could jamie do to make his experimental results more closely match the theoretical probability? (\bigcirc) he can increase the number of trials. (\bigcirc) he can decrease the number of trials. (\bigcirc) he can increase the number of sides on the die. (\bigcirc) he can decrease the number of sides on the die.

Explanation:

In probability, the Law of Large Numbers states that as the number of trials (experiments) increases, the experimental probability approaches the theoretical probability. Decreasing trials or changing die sides (unrelated to the probability of rolling a 2 on a 6 - sided die) won't help. So increasing trials makes experimental results match theoretical better.

Answer:

A. He can increase the number of trials.
