Key Concepts

Probability

Probability is a measure that quantifies the likelihood of an event occurring. It is typically calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes, assuming that all outcomes are equally likely. This concept underlies much of statistical reasoning and decision-making in uncertain scenarios.

Sample Space

The sample space is the set of all possible outcomes of a random experiment. It is a fundamental concept in probability theory because it provides the complete context within which events occur and are assessed. Understanding the sample space is crucial for determining the probability of events.

Event

An event is any subset of the sample space, representing a collection of outcomes for which the probability is to be determined. It can be as simple as a single outcome or as complex as a combination of outcomes, and its probability is calculated by considering the ratio of the number of outcomes in the event to the total outcomes in the sample space.

Equally Likely Outcomes

The assumption of equally likely outcomes means that each outcome in the sample space has the same chance of occurring. This simplifies the computation of probabilities, as it allows one to directly use the ratio of the number of favorable outcomes to the total number of outcomes without needing to assign different weights to different results.
