To determine the number of possible outcomes illustrated in a tree diagram, you typically count the different branches or paths in the diagram. Each branch represents a possible outcome of a decision or event.
Since you have provided options (2, 4, or 6, or 8), and without seeing the specific tree diagram, I can guide you on how to find the number of outcomes:
- Count the Levels: Identify how many decisions/events are represented in the tree.
- Count Branches: For each decision/event, count the number of branches that stem from it.
- Multiply Branches Together: Multiply the number of branches from each level to determine the total number of possible outcomes.
For instance, if the first decision has 2 branches and the second decision also has 2 branches, then the total outcomes would be \(2 \times 2 = 4\).
If you could provide more details or the structure of the tree diagram, I could give a more precise answer. However, based solely on the options presented, you would typically arrive at an answer by performing the steps outlined above.
