Probabilities That Add Up to One

 

Students learn how mutually exclusive events are represented in a Venn diagram and that probabilities add up to one.

As learning progresses, they use mutually exclusive events to calculate the probability of an event not happening.

Differentiated Learning Objective
  • All students should be able to identify mutually exclusive events.
  • Most students should be able to understand that the probabilities of all possible outcomes sum to 1.
  • Some students should be able to calculate the probability of an event not happening.
