Description: In Exercises 43–44, it is equally probable that the pointer on the spinner shown will land on any one of the eight regions, numbered 1 through 8. If the pointer lands on a borderline, spin again. Find the probability that the pointer will stop on an odd number or a number less than 6.

Key Concepts

Equally Likely Outcomes

This concept refers to a situation where every outcome in the sample space has the same probability of occurring. When outcomes are equally likely, probability calculations can be simplified by counting the number of favorable outcomes divided by the total number of possible outcomes.

Sample Space

The sample space is the complete set of all possible outcomes of an experiment. In probability, defining the sample space is crucial as it represents all the events that can occur, allowing one to correctly determine probabilities.

Events

An event is a subset of the sample space that groups specific outcomes of interest. In probability problems, events are defined based on given conditions, and the probability of an event is determined by identifying and counting all outcomes that satisfy the event's conditions.

Compound Events

Compound events involve the occurrence of more than one event at the same time or in combination. Problems often require calculating the probability of events formed by the union (or intersection) of two or more individual events, such as an outcome meeting at least one of multiple criteria.

Inclusion-Exclusion Principle

This principle is used to accurately calculate the probability of the union of two events, especially when they overlap. It states that the probability of either event A or event B occurring is equal to the sum of the probabilities of each event individually minus the probability of both events occurring simultaneously.
