Using tree diagrams for combined events

Probability • Probability

Key concepts

What you'll likely be quizzed about

  • To create a tree diagram, begin with a starting point that represents the initial event.
  • Each branch of the tree illustrates a possible outcome of this event.
  • For example, when flipping a coin, the two branches would represent 'Heads' and 'Tails'.
  • Continue adding branches for subsequent events, maintaining the order of events as they occur.
  • This structure allows for a clear visualization of all outcomes.

Ensure all branches are labeled clearly.

Probabilities must total one for exhaustive outcomes.

For independent events, use product rule; for dependent, adjust accordingly.
