CIMT textbook Chapter 21

Video tutorials

Understand the probability scale from 0 to 1, including that a probability of 0 means impossible and a probability of 1 means a certainty. Describe an outcome in terms of likelihood using words.


Place an outcome on a probability line between 0 and 1.

Calculate the theoretical probability of an outcome for a simple event involving a single experiment with equally likely outcomes.


Use an experiment to calculate the relative frequency of an event, and compare this relative frequency to a prediction made using theoretical probability methods:


Use a probability to calculate an expected frequency for an outcome.

Sample space diagrams.

Mutually exclusive outcomes:
