DESCRIPTION:

This Khan Academy video offers more information on expected value and contains a sample problem with a walkthrough.

OVERVIEW:

Expected Value: E(X) is a free educational video by Khan Academy.It helps students in grades HS practice the following standards HSS.MD.A.2,HSS.MD.A.3,HSS.MD.A.4.

This page not only allows students and teachers view Expected Value: E(X) but also find engaging Sample Questions, Apps, Pins, Worksheets, Books related to the following topics.

1. HSS.MD.A.2 : Calculate the expected value of a random variable; interpret it as the mean of the probability distribution..

2. HSS.MD.A.3 : 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..

3. HSS.MD.A.4 : Develop a probability distribution for a random variable defined for a sample space in which probabilities are assigned empirically; find the expected value. For example, find a current data distribution on the number of TV sets per household in the United States, and calculate the expected number of sets per household. How many TV sets would you expect to find in 100 randomly selected households?.
