Probability Distribution




 


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.
