Question

jonas is conducting an experiment using a 10-sided die. he determines that the theoretical probability of rolling a 3 is \\(\frac{1}{10}\\). he rolls the die 20 times. four of those rolls result in a 3. which adjustment can jonas make to his experiment so the theoretical and experimental probabilities are likely to be closer?
\\(\circ\\) he can decrease the sample space.
\\(\circ\\) he can increase the sample space.
\\(\circ\\) he can decrease the number of trials.
\\(\circ\\) he can increase the number of trials.

Explanation:

In probability, as the number of trials (rolls here) increases, experimental probability (from trials) tends to approach theoretical probability (from math). Decreasing trials or sample space won't help; increasing trials makes them closer.

Answer:

D. He can increase the number of trials.
