3.1   Introduction

Chapter 2 dealt with discrete random variables, which have a finite or countable range. This chapter deals with continuous random variables, which do not have a countable range. Discrete and continuous random variables share many of the same concepts. Both are functions that associate a real number with each outcome of a random experiment. ...
