• Range: $0 \le P(A) \le 1$.
• Complement Rule: $P(A') = 1 - P(A)$ (The probability of A not happening).
• Addition Rule: $P(A \cup B) = P(A) + P(B) - P(A \cap B)$. Used to find the probability of A or B occurring.
• Multiplication Rule: $P(A \cap B) = P(A) \times P(B|A)$. Used for intersections.

Covers central tendency (mean, median, mode), dispersion, and data summarization through graphs and tables. Probability Theory: Range: $0 \le P(A) \le 1$

Statistics and probability have many real-life applications, including:

1. Medicine: Statistics and probability are used in medical research to analyze data and make conclusions about the effectiveness of treatments.
2. Business: Statistics and probability are used in business to analyze data and make decisions about investments, marketing, and finance.
3. Engineering: Statistics and probability are used in engineering to analyze data and make decisions about design, testing, and quality control.
4. Social Sciences: Statistics and probability are used in social sciences to analyze data and make conclusions about social phenomena.

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1 that represents the chance or probability of an event happening. A probability of 0 indicates that the event is impossible, while a probability of 1 indicates that the event is certain. Probability is used to model real-world phenomena, such as the probability of a coin landing heads up or the probability of a person having a certain disease.
