## What Is Data Analysis?
Data analysis is about collecting, organizing, and understanding information. Graphs, charts, and tables are tools to help you see patterns.
### Probability
Probability tells you how likely an event is to happen. It ranges from 0 (impossible) to 1 (certain).
- Formula: \( P = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \)
## Applications
Data and probability are used in sports statistics, weather forecasting, and making predictions.
Examples
- Reading a bar graph to compare test scores.
- Calculating the probability of drawing a red marble from a bag.
