Statistics

Probability and Random Variables

A probability distribution describes the range of possible values a random variable can have. In the activities in this unit, students investigate discrete and continuous distributions, explore the Law of Large Numbers, examine two-way tables and use simulation to estimate solutions to probability problems. They also focus on probability concepts such as conditional probability, independence and dependence and mutually exclusive events.
