The purpose of this chapter is to discuss the nature of probability theory. In Section 1 we point out the existence of a certain body of phenomena that may be called random. In Section 2 we state the view, which is adopted in this book, that probability theory is the study of mathematical models of random phenomena. The language and notions that are used to formulate mathematical models are discussed in Sections 3 to 7.

Many of the basic concepts of probability theory, as well as a large number of important problems of applied probability theory, may be considered in the context of finite sample description spaces and thus can be studied with a minimum of mathematical technique. In Chapters 2 and 3 only finite sample description spaces are considered. In this chapter we further restrict ourselves to finite sample description spaces with equally likely descriptions.

In the foregoing we have considered mainly random phenomena whose sample description spaces were finite. We next consider random phenomena for which this is not necessarily the case. The simplest example of a random phenomenon whose sample description space is not necessarily finite is one which is numerical valued. The height of waves on a windswept sea, the number of alpha particles emitted from a radioactive source, the number of telephone calls arriving at a switchboard, the velocity of a particle in Brownian motion, the scores of students on an examination, the collar sizes of men, the dress sizes of women, and so on, constitute examples of numerical-valued random phenomena. In this chapter we discuss the notions and techniques used to treat numerical-valued random phenomena.

It has been emphasized that in order to describe a numerical valued random phenomenon one must specify its probability function \\(P[\\cdot]\\) or, equivalently, its distribution function \\(F(\\cdot)\\) . In the special case in which the random phenomenon obeys a discrete or a continuous probability law its probability function is determined by a knowledge of the probability mass function \\(p(\\cdot)\\) or of the probability density function \\(f(\\cdot)\\) . Thus, to describe a numerical valued random phenomenon, certain functions must be specified. It is desirable to be able to summarize some of the outstanding features of the probability law of a numerical valued random phenomenon by specifying only a few numbers rather than an entire function. Such numbers are provided by the expectation of various functions \\(g(\\cdot)\\) with respect to the probability law of the random phenomenon.

It has been stressed in the foregoing chapters that the probability of a random event can be discussed only with reference to a sample description space on which a probability function has been defined. However, in many applications of probability theory the terminology of sample description spaces does not explicitly enter (although, as we shall see, the notion is always implicitly present). Rather, many applications of probability theory are based on the notion of a random variable . This chapter gives a rigorous definition of the notion of a random variable and presents the main concepts and techniques used to treat random variables.

In dealing with random variables, it is as important to know their means and variances as it is to know their probability laws. In this chapter we define the notion of the expectation of a random variable and describe the significant role that this notion plays in probability theory.

Chapters 9 and 10 are much less elementary in character than the first eight chapters of this book. They constitute an introduction to the limit theorems of probability theory and to the role of characteristic functions in probability theory. These chapters seek to provide a careful and rigorous derivation of the law of large numbers and the central limit theorem.

In this chapter we treat the problem of finding the probability law of a random variable that arises as the sum of independent random variables. A major tool in this study is the characteristic function of a random variable, introduced in section 2. In section 3 it is shown that the probability law of a random variable can be determined from its characteristic function. Section 4 discusses some consequences of the basic result that the characteristic function of a sum of independent random variables is the product of the characteristic functions of the individual random variables. Section 5 gives the proofs of the inversion formulas stated in section 3.

The basic concepts of probability theory, such as the probability of a random event (or the mean of a random variable), have been given intuitive meanings as approximately representing certain averages computed from a large sample of independent observed values of the event (or of the random variable). In this chapter we treat the problem of giving an exact mathematical meaning to the word “approximately” as it is employed in the foregoing sentence. At the same time, our discussion leads to an answer to the question of what constitutes an approximate solution to the problem of finding the probability law of the sum of random variables. A basic role in this study is played by the notion of the convergence of a sequence of random variables .
