Texas Instruments: Probability: Pairs of Events and Expected Values

A PDF explaining and giving examples to show how the expected value of a random variable indicates its weighted average.

The gap between probability and statistics begins to become bridged in this video, where Sal explains the concepts of central and relative frequencies. Students who are transitioning between algebra and statistics will find this video...

Designing a game is the focus of this probability lesson. Groups develop and build a unique game, including directions for how to play, a calculation of the expected value of winning, and a personal reflection. The plan provides a...

Based off of the hit television show NUMB3RS, this lesson exposes students to the concept of expected values (or expected outcomes). The method for computing the expectation is explained, and then many examples are given for students to...

Your statisticians examine the characteristics of conditional probability and the probability of simultaneous independent events. They perform computer activities to find probabilities for simple compound events. They examine the...

In this activity, students use simulation to justify the concept of the Law of Large Numbers. They understand that as the sample size increases, the relative frequency of which an event occurs approaches the probability of that event...

Find expected value based on calculated probabilities. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Find expected value based on empirical probabilities. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Calculate expected values and then use them to make decisions. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This lesson will explain expected value. It is 1 of 3 in the series titled "Expected Value." [6:12]
