Tree diagrams are really helpful for understanding situations where there are many possible outcomes. They show all these possibilities in a simple visual way, which makes it easier to figure out probabilities.

Why Use Tree Diagrams?

• Clear Representation: Each branch on the tree shows a different outcome. For example, if you flip a coin and roll a die, the branches can include outcomes like Heads-1, Heads-2, and so on.

• Easy Calculations: You can find probabilities by multiplying the numbers along the branches. For instance, if the chance of getting Heads from the coin is ½ and the chance of rolling a 3 on the die is ⅙, then the combination of these two events looks like this:

  $$P(\text{Heads and 3}) = \frac{1}{2} \times \frac{1}{6} = \frac{1}{12}$$

This method makes it easier to understand complicated events!
