Answer:
<em>D.</em><em> He can increase the number of trials.</em>
Step-by-step explanation:
Jonas is conducting an experiment using a 10-sided die. So the theoretical probability of rolling a 3 in a single trial is,
So the theoretical expected outcome of 3 in 20 roll would be,
But when he rolled the die 20 times, where four of those rolls resulted 3.
Which is 2 times more than the theoretical expectation.
Increasing the number of trials from 20, the expected outcome will increase.
As the number of trials is multiplied with , so bigger the number is from 20, bigger the value.
As we know,
If we want to increase the expected value, we have to increase the number of trials.
