Combinations without repetition is used to explain how lotteries work. The numbers are drawn one at a time and if one has the lucky numbers, no matter in what order, they win. This can be understood by assuming the order does matter, such as permutation and consequently alter it so the order no longer matters. An example of this is when we go to back to trying to find which 3 options of soccer players were chosen and not the order. We already know when 3 players are chosen out of 10 options of

Statistics Chapter 2 Methods for Describing Sets of Data Quantitative data is information about quantities; that is, information that can be measured and written down with numbers. Qualitative data is information about qualities; information that can't actually be measured. A class is one of the categories into which qualitative data can be classified. The class frequency is the number of observations in the data set that fall into a particular class. The class relative frequency is the class

Harley Davidson offers, there are >500,000 combinations for a single motorcycle. Large companies like this can support such a large infrastructure for offering so many combinations while smaller plants may not be able to accommodate so many permutations. If a smaller business offered a smaller portfolio with a single bike and options that contained 2 handle bars, 3 luggage bags, and 4 exhaust pipe configurations, there would be a total of 24 permutations which would be easier to accommodate than the

Certificate Authority: Certificate authority is used to issue certificates and to verify the identity of the owner. It is a part of the public key infrastructure. These certificates helps the users to trust the website information confirming it is secure and a trusted party. CSR refers to Certificate Signing Request. Whenever a CSR is sent to the certificate authority, it is sent along with the public key and the other specific information possessed only by the owner. The CA then verifies the identity

Introduction TSP (Travelling salesman problem) is an optimization problem that it is difficult to solve using classical methods. Different Genetic Algorithm (GA) have been right to solve the TSP each with advantages and disadvantages (Davis, 2005) In this research paper, I highlight a new algorithm by merging different genetic Algorithm results to the better solution for TSP. In amalgam algorithm, appropriateness of algorithm and traveled distance for TSP has been considered. Results obtained suggest

Information Retrieval P. BAXENDALE, Editor A Relational Model of Data for Large Shared Data Banks E. F. CODD IBM Research Laboratory, San Jose, California Future users of large data banks must be protected from having to know how the data is organized in the machine (the internal representation). A prompting service which supplies such information is not a satisfactory solution. Activities of users at terminals and most application programs should remain unaffected when the internal representation

would dip it in water and wash off all the information” (Plus magazine) (Plus magazine) How enigma was solved Initial Idea – Rejewski’s Theorem It was the poles who first started solving enigma. Rejewski used a mathematical theorem—that two permutations are conjugate if and only if they have the same cycle structure—that one mathematics professor has since described as "the theorem that won World War II." (Solving Enigmas Wiring) The radio operators would code the first 6 letters in the global

PERMUTATIONS AND COMBINATIONS KEY POINTS * When a job is performed in different ways then each way is called the permutation. * Fundamental principle of counting: If a job can be performed in m different ways and for each such way, second job can be done in different ways, then the two jobs can be completed in m x n ways. * Fundamental principle of Addition: If there are two events such that they can be performed independently in m and n ways respectively, then either of two events can
