In a nutshell: Probability measures the chance of events happening.
## Exploring Probability
Probability is the study of chance. It helps us predict how likely something is to happen, from rolling dice to forecasting rain!
### Calculating Probability
The probability of an event is the number of favorable outcomes divided by the total number of possible outcomes:
\[
P(\text{event}) = \frac{\text{Number of favorable outcomes}}{\text{Total outcomes}}
\]
### Randomness in Data
In statistics, randomness means outcomes happen by chance and can't be exactly predicted.
### Real-World Applications
- Weather forecasts use probability to predict rain.
- Game designers use randomness to make games exciting.
P(\text{event}) = \frac{\text{favorable outcomes}}{\text{total outcomes}}
Examples
- The probability of flipping a coin and getting heads is 0.5.
- Predicting the chance of rain tomorrow based on weather data.
Key terms
- Probability
- A measure of how likely an event is to occur.
