Eugene · Answer 1

If you asked a lot of students from this particular university how many classes they are registered for, the average of classes will be 4.15.

Step-by-step explanation:

The expected value is the average of the discrete random variable in the long run. If an event occurs many, many times the average value of the outcomes gets closer to the expected value, and when the sample is big you get the expected value.
