What's the difference?
**Probability** is the measure of the likelihood that an event will occur. It's about predicting the future based on known outcomes. The probability of an event $A$ is written as $P(A)$, and is calculated as: $$P(A) = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$$
**Statistics** is the science of collecting, analyzing, interpreting, and presenting data. It's about drawing conclusions from past or current data to describe a sample or make inferences about a population.
