The point of view is differ- ent from the one we took when we started studying physics. There we said that if we do the same thing in the same way over and over again send a space shuttle into orbit, for example the result will always be the same. To predict the result, we have to take account of all relevant facts.

## Hm... Are You a Human?

The mathematics of probability begins when the situation is so complex that we just cant replicate everything important exactly like when we fabricate and test an integrated circuit. In this case, repetitions of the same procedure yield different results. While each outcome may be unpredictable, there are consistent patterns to be observed when we repeat the procedure a large number of times. Understanding these patterns helps engineers establish test procedures to ensure that a factory meets quality objectives.

## Yates - Probability and Stochastic Processes (2nd Edition)

In this repeatable procedure making and testing a chip with unpredictable outcomes the quality of individual chips , the probability is a number between 0 and 1 that states the proportion of times we expect a certain thing to happen, such as the proportion of chips that pass a test.

As an introduction to probability and stochastic processes, this book serves three pur- poses: It introduces students to the logic of probability theory.

It helps students develop intuition into how the theory applies to practical situations. It teaches students how to apply probability theory to solving engineering problems. To exhibit the logic of the subject, we show clearly in the text three categories of theoretical material: denitions, axioms, and theorems. Denitions establish the logic of probability theory, while axioms are facts that we accept without proof. Theorems are consequences that follow logically from denitions and axioms.

Each theorem has a proof that refers to denitions, axioms, and other theorems. Although there are dozens of denitions and theorems, there are only three axioms of probability theory.

These three axioms are the foundation on which the entire subject rests. To meet our goal of presenting the logic of the subject, we could set out the material as dozens of denitions followed by three axioms followed by dozens of theorems. Each theorem would be accompanied by a complete proof. While rigorous, this approach would completely fail to meet our second aim of conveying the intuition necessary to work on practical problems.

To address this goal, we augment the purely mathematical material with a large number of examples of practical phenomena that can be analyzed by means of probability theory. We also interleave denitions and theorems, presenting some theorems with complete proofs, others with partial proofs, and omitting some proofs altogether.

We nd that most engineering students study probability with the aim of using it to solve practical problems, and we cater mostly to this goal.

We also encourage students to take an interest in the logic of the subject it is very elegant and we feel that the material presented will be sufcient to enable these students to ll in the gaps we have left in the proofs. Therefore, as you read this book you will nd a progression of denitions, axioms, theorems, more denitions, and more theorems, all interleaved with examples and comments designed to contribute to your understanding of the theory.

We also include brief quizzes that you should try to solve as you read the book. Each one will help you decide whether you have grasped the material presented just before the quiz. The problems at the end of each chapter give you more practice applying the material introduced in the chapter.

They vary considerably in their level of difculty.

Some of them take you more deeply into the subject than the examples and quizzes do. Most people who study proba- bility have already encountered set theory and are familiar with such terms as set, element, 1.

For them, the following paragraphs will review ma- terial already learned and introduce the notation and terminology we use here. For people who have no prior acquaintance with sets, this material introduces basic denitions and the properties of sets that are important in the study of probability. A set is a collection of things. We use capital letters to denote sets. The things that together make up the set are elements.

When we use mathematical notation to refer to set elements, we usually use small letters.

Thus we can have a set A with elements x, y, and z. The symbol denotes set inclusion. Thus x A means x is an element of set A. It is essential when working with sets to have a denition of each set. The denition allows someone to consider anything conceivable and determine whether that thing is an element of the set. There are many ways to dene a set.

It follows that the planet closest to the Sun A is a true statement. Since there is no number to the right of the dots, we continue the sequence indenitely, forming an innite set containing all perfect squares except 0. In addition to set inclusion, we also have the notion of a subset, which describes a relationship between two sets.

## Frequently bought together

By denition, A is a subset of B if every member of A is also a member of B. We use the symbol to denote subset.

Thus A B is mathematical notation for the statement the set A is a subset of the set B. Using the denitions of sets C and D in Equations 1. This is the mathematical way of stating that A and B are identical if and only if every element of A is an element of B and every element of B is an element of A.

This denition implies that a set is unaffected by the order of the elements in a denition.

To work with sets mathematically it is necessary to dene a universal set. This is the set of all things that we could possibly consider in a given context. In any study, all set operations relate to the universal set for that study.

The members of the universal set include all of the elements of all of the sets in the study. We will use the letter S to denote the universal set.

By denition, every set is a subset of the universal set. That is, for any set X, X S. The null set, which is also important, may seem like it is not a set at all. By denition it has no elements. The notation for the null set is.

By denition is a subset of every set.

For any set A, A. It is customary to refer to Venn diagrams to display relationships among sets. By con- vention, the region enclosed by the large rectangle is the universal set S. Closed surfaces within this rectangle denote sets. There are three operations for doing this: union, intersection, and complement. Union and intersection combine two existing sets to produce a third set.

The complement operation forms a new set from one existing set. The union of A and B is denoted by A B. In this Venn diagram, A B is the complete shaded area.

Formally, the denition states x A B if and only if x A or x B. The set operation union corresponds to the logical or operation. The intersec- tion is denoted by A B. Another notation for intersection is AB. Formally, the denition is x A B if and only if x A and x B.

The set operation intersection corresponds to the logical and function.

The complement of S is the null set. A fourth set operation is called the difference. It is a com- A-B bination of intersection and complement. In working with probability we will frequently refer to two important properties of collec- tions of sets. Here are the denitions. While each outcome may be unpredictable, there are consistent patterns to be observed when we repeat the procedure a large number of times.

Understanding these patterns helps engineers establish test procedures to ensure that a factory meets quality objectives. In this repeatable procedure making and testing a chip with unpredictable outcomes the quality of individual chips , the probability is a number between 0 and 1 that states the proportion of times we expect a certain thing to happen, such as the proportion of chips that pass a test.

In this chapter and for most of the remainder of the course, we will examine probability models that assign numbers to the outcomes in the sample space. In this case, repetitions of the same procedure yield different results. It presents probability as a branch of number theory. That is, for each outcome, either the particular event occurs or it does not.
