32 BASIC OPERATIONS ON SETS
Counting and Combinatorics The major goal of this chapter is to establish several (combinatorial) techniques for counting large finite sets without actually listing their elements. These techniques provide effective methods for counting the size of events, an important concept in probability theory. 3 The Fundamental Principle of Counting Sometimes one encounters the question of listing all the outcomes of a certain experiment. One way for doing that is by constructing a so-called tree diagram. Example 3.1 A lottery allows you to select a two-digit number. Each digit may be either 1,2 or 3. Use a tree diagram to show all the possible outcomes and tell how many different numbers can be selected. Solution. 33
