Random Variables and Probability Distributions

Learn to distinguish between discrete and continuous random variables and understand how a probability distribution describes the likelihood of all possible outcomes. You will also learn to calculate and interpret the expected value of a discrete random variable.

Ontario Curriculum ExpectationsOntario Curriculum, Grade 12, MDM4U: Probability Distributions - Represent and solve problems involving the probability distributions of discrete random variables.

About This Topic

Learn to distinguish between discrete and continuous random variables and understand how a probability distribution describes the likelihood of all possible outcomes. You will also learn to calculate and interpret the expected value of a discrete random variable.

Key Questions

  1. Explain the difference between a discrete random variable and a continuous random variable, providing an example of each.
  2. Analyse a given probability distribution to determine if it is valid and calculate its expected value.
  3. Compare the theoretical probability distribution of rolling two dice with the experimental results from a simulation.
