Rosen. material, may be used as a textbook for a formal course in discrete mathematics or as a supplement to all current texts. Basic Counting Principles: The Sum Rule The Sum Rule: If a task can be done either in one of n 1 ways or in one of n 2 ways to do the second task, where none of the set of n 1 ways is the same as any of the n 2 ways, then there are n 1 + n 2 ways to do the task. Discrete Mathematics is a branch of mathematics involving discrete elements that uses algebra and arithmetic. Fundamental Principle of Counting (PowerPoint File) 2. CS 441 Discrete mathematics for CS M. Hauskrecht Counting • Assume we have a set of objects with certain properties • Counting is used to determine the number of these objects Examples: • Number of available phone numbers with 7 digits in the local calling area • Number of possible match starters (football, basketball) given Throw a die and flip a coin. Discrete Mathematics (c)Marcin Sydow Productand SumRule Inclusion-Exclusion Principle Pigeonhole Principle Permutations Generalised Permutations andCombi-nations Combinatorial Proof Binomial Coeﬃcients DiscreteMathematics Counting (c)MarcinSydow Discrete Mathematics Lattices with introduction, sets theory, types of sets, set operations, algebra of sets, multisets, induction, relations, functions and algorithms etc. De nition 1 (Principle of Sum). Example: The mathematics … Discrete Mathematics Lecture12 Counting §5.1 The Basics of counting Example 1 ： A counting Next come chapters on logic, counting, and probability.We then have three chapters on graph theory: graphs, directed It is increasingly being applied in the practical fields of mathematics and computer science.

Scribd is the world's largest social reading and publishing site. He was solely responsible in ensuring that sets had a home in mathematics. In this section, we shall develop a few counting techniques. Example: What sequence is represented by the following series : SolutionBy now you must have got this, the coefficient of a 0 = 1, a 1 = 0, a 2 = 4, a 3 = 0, a 4 = 1, a 5 = 1/999, a 6 = 100.
