Event Relations

In this articule, we discuss why we need tools to calculate probabilities associated with combinations of events.

In the last activity, we introduced the idea of simple events. Now, we’ll turn our attention to more complex events and look at how we can calculate probabilities for combinations of simple events. Specifically, we’ll focus on how to answer questions in the form of:

  • What is the probability that both of these events occur?
  • What is the probability that neither event occurs?
  • What is the probability that at least one of these events occurs?

These types of questions deal with relations between events, and we have a bit more terminology about how we refer to them. You’ll hear about unions, intersections and complements in the next video. Click through if you’re ready to get started!
