Lesson: Introduction to Probability Mathematics • 7th Grade

Students will be able to

• understand what probability is as well as associated concepts such as an event, an outcome, and a sample space,
• understand two of the axioms of probability:
  • the probability of an event must be between 0 and 1 (inclusive),
  • all probabilities of the outcomes of an event must add up to 1,
• use probability notation,
• use a numerical value to describe the probability of an event that is certain, impossible, or 50–50,
• understand that the probability of an event can be given as a fraction, a decimal, or a percentage.
