Our objectives in this section are to

  • Utilize the complement of an event to calculate the likelihood of an event.
  • Calculate the probability of the union of two events.
  • Calculate the probability of the intersection of two events.
  • Combine compliment and union to compute the probability of an event.
  • Compute conditional probabilities from formulas.
  • Use contingency tables to compute conditional probabilities.
  • Use probability trees to compute conditional probabilities.
  • Determine when two events are dependent or independent.

Use the workbook and videos to learn more about union, intersection, and conditional probability.
