Learning Objectives

By the end of this session, you will be able to:

  • Define probability as a measure of how likely something is to happen
  • Use vocabulary: certain, likely, unlikely, impossible, equally likely
  • Calculate simple probabilities as fractions
  • Understand that probability does not predict individual events

Why This Matters

Probability is how we make sense of uncertainty. Understanding chance helps you make better decisions when outcomes are not guaranteed.
