Videos and lessons to help High School students learn how to
develop a probability distribution for a random variable defined
for a sample space in which theoretical probabilities can be
calculated; find the expected value.
For example, find the theoretical probability distribution for
the number of correct answers obtained by guessing on all five
questions of a multiple-choice test where each question has four
choices, and find the expected grade under various grading
schemes.
