Understanding Probability Basics
Probability is a mathematical framework used to quantify uncertainty. The fundamental concepts of probability can be broken down into several key areas:
1. Definitions and Notations
- Experiment: An action or process that leads to one or more outcomes.
- Sample Space (S): The set of all possible outcomes of an experiment. For example, in a coin toss, the sample space is {Heads, Tails}.
- Event (A): A subset of the sample space. For instance, getting a Head in a coin toss can be defined as an event.
- Probability (P): A measure of the likelihood that an event will occur, ranging from 0 (impossible event) to 1 (certain event).
2. Axioms of Probability
The probability of events is governed by three fundamental axioms:
1. Non-negativity: For any event A, \( P(A) \geq 0 \).
2. Normalization: The probability of the sample space is 1, i.e., \( P(S) = 1 \).
3. Additivity: For any two mutually exclusive events A and B, \( P(A \cup B) = P(A) + P(B) \).
3. Types of Probability
- Theoretical Probability: Based on the reasoning behind probability (e.g., the chance of rolling a 3 on a fair six-sided die is \( \frac{1}{6} \)).
- Experimental Probability: Based on the actual results of an experiment (e.g., if you roll a die 60 times and get a 3 ten times, the experimental probability is \( \frac{10}{60} = \frac{1}{6} \)).
- Subjective Probability: Based on personal judgment or experience rather than on exact calculations.
Probability Distributions
Probability distributions are mathematical functions that describe the likelihood of obtaining the possible values that a random variable can take.
1. Discrete Probability Distributions
- Binomial Distribution: Represents the number of successes in a fixed number of independent Bernoulli trials.
- Poisson Distribution: Represents the number of events occurring in a fixed interval of time or space.
2. Continuous Probability Distributions
- Normal Distribution: A bell-shaped distribution characterized by its mean and standard deviation.
- Exponential Distribution: Describes the time between events in a Poisson point process.
3. Key Properties of Distributions
- Mean (Expected Value): The average value of a random variable.
- Variance: A measure of the spread of a set of values.
- Standard Deviation: The square root of the variance, indicating the dispersion of values around the mean.
