Tree diagrams are a great way to help us understand compound probabilities, especially in Year 9 Math. They show us all the possible outcomes of an event in a clear and organized way.
Easy to Understand: Each branch of the tree shows a different outcome. This makes it easy to follow along and see what happens.
Finding Probabilities: We can give each branch a probability (a number between 0 and 1 that shows how likely something is). For example, if we say event A has a probability of 0.5 and event B has a probability of 0.4, we can find out the chance of both happening together. We do this by multiplying their probabilities: 0.5 (for A) times 0.4 (for B) equals 0.2.
Working with Many Events: Tree diagrams can show us several steps or events at once. This helps us see all the outcomes and their probabilities without getting confused.
In short, tree diagrams make it easier to understand compound probabilities. They show outcomes clearly, help with calculations, and can manage complicated situations.
