Probability of Two Stage Events

Using tree diagrams and tables to calculate the probability of independent and dependent events.

Key Questions

  1. 1How does the outcome of the first event change the sample space of the second event in dependent scenarios?
  2. 2Why do we multiply probabilities along the branches of a tree diagram?
  3. 3How can we use arrays to systematically list all possible outcomes for a two stage experiment?
