Statistics and Probability

Definition

A sample space is the set of all possible outcomes in a probability experiment.

Description

The sample space is a foundational concept in probability, providing the framework within which probabilities are assigned to events. It is used in various fields, such as finance, to model different investment outcomes, or in engineering to predict system failures.

Understanding the sample space is crucial for students to accurately calculate probabilities and analyze different scenarios. It helps them develop a comprehensive understanding of how different events relate to each other within a probability model.

Measures of Central Tendency

Description

This example demonstrates the calculation of the mean for a probability distribution of a fair six-sided die. The probability of each outcome (1 to 6) is equally 1/6. The mean is calculated by multiplying each possible outcome by its probability and summing the results. For this fair die, the mean is determined to be 3.5.

Measures of Central Tendency

Description

This example illustrates the calculation of the mean for a probability distribution of an unfair six-sided die. Unlike a fair die, the probabilities are not equally distributed, with a higher probability (2/6) for rolling a 1. The mean is calculated using the same method as before, resulting in approximately 2.83.
