1 Stochastic Processes 1.1 Probability Spaces and Random Variables In this section we recall the basic vocabulary and results of probability theory. A probability space associated with a random experiment is a triple (;F;P) where: (i) is the set of all possible outcomes of the random experiment, and it is called the sample space.

2.2 Random Variables Informally a random variable is a variable which takes on values (either discrete or continuous) at random. It can be thought of as a function of the outcomes of a random experiment. The probability that a continuous random variable takes on specific values is given by the (cumula-tive) probability distribution: F X (x) P X

The central objects of probability theory are to develop the mathematic tool to analyze random variables, stochastic processes, and random events. It provides the systematic and mathematical approach for analyzing a wide class of random phenomena. 1.1 Probability Triple We introduce the probability triple

These signals can be described with the help of probability and other concepts in statistics. Particularly the signal under observation is considered as a realization of a random process or a stochastic process. The terms random processes, stochastic processes and random signals are used synonymously.

Probability measures how likely something is to happen. An event that is certain to happen has a probability of 1. An event that is impossible has a probability of 0. An event that has an even or equal chance of occurring has a probability of 1 2 or 50%. Chance and probability – ordering events impossible unlikely

Random Variables In probability theory, certain functions of special interest are given special names: De nition 1 A function whose domain is a sample space and whose range is some set of real numbers is called a random variable. If the random variable is denoted by Xand has . such number

Random Numbers on the TI-89 Random number commands native to the operating system of the TI-89 are: 2 I- 7:Probability- 4:rand(. The command rand() returns a random number 0 and 1 after ENTER is punched. Continuing to punch ENTER generates more random numbers. The command rand(20), for instance, will generate a random integer between 1 and 20.
