Question

Which of the following statements about the expected value of a random experiment is true? A. The expected value is the value you will get after one trial. B. The expected value is the average of the values after 100 trials. C. As the number of trials gets larger, the average of the trials approaches the expected value. D. The expected value never actually equals the average of the trials.

Answer 1

Answer: C

Step-by-step explanation: As the number of trials gets larger the average of the trials approaches the expected value

Answer 2

C. As the number of trials gets larger, the average of the trials approaches the expected value.

Explanation:

The statement that is true would be that, as the number of trials gets larger, the average of the trials approaches the expected value. A certain random experiment can have a various number of trials, while the expected value is going to be the average of those trials. The more trials that an experiment has, the more data that can be gathered and the average can be better calculated. This average keeps getting closer and closer to the expected value as more trials are completed and the data keeps repeating certain values.
