Introduction: 

What's the chance it will rain tomorrow? How likely is it for someone to win the lottery? Take a stab at percent chance to understand probability—or how probable it is for a specific event to happen.

In this lesson you will:
  • Practice measuring and comparing probabilities
  • Use percents to talk about probability
  • Evaluate risks by ranking probabilities in order of less likely to more likely
