Visual aids like probability trees are really useful for figuring out simple probability events. They help students see all the possible outcomes in a clear and organized way.

How It Works:

1. Structure: A probability tree starts at a single point and then branches out to show different events.
2. Outcomes: Each branch shows what can happen, helping us visualize all the ways an event can turn out.

Example:

Let’s think about flipping a coin.

• The first branch splits into two: Heads (H) and Tails (T).
• If we flip again, each result splits again:
  • HH (Heads, Heads), HT (Heads, Tails), TH (Tails, Heads), TT (Tails, Tails).

Calculation:

To find out the chance of getting two heads (HH), we can follow the branches:

P(HH) = P(H) × P(H) = ½ × ½ = ¼.

Using probability trees makes it easy to see and calculate these outcomes!
