Which of the following statements about the expected value of a random experiment is true? A. The expected value is the value yo
u 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.
C. As the number of trials gets larger, the average of the trials approaches the expected value.
Step-by-step 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.
The quantity demanded would increase due to the cheaper price people would want to take advantage and buy it when it was on sale. There is not enough information to determine whether the supply or demand would maintain so D is your answer.
