Sequences are ordered element lists, which are used in many respects in discrete mathematics. They can, for example, be used to solve certain counting problems. They are also a key computer science data structure.The sequence terms can be specified with a formula for each sequence term. Definition A sequence is a discrete structure used to […]
Introduction A function was originally the idealization of how a varying quantity depends on another quantity. In many cases, we assign a particular element of a second set( which might be the same as the first) to each element of a set. For Example, suppose each student in a class is assigned a letter grade […]
The probability event is a set of outcomes of an experiment (a subset of the sample space) to which a probability is assigned. The particular output of sample space is called event A single outcome may be an element of many different events, and different events in an experiment are usually not equally likely, since they may include very different groups of outcomes. An event defines a complementary event, […]
The numerical evaluation of degree of uncertainty is called probability The word probability derives from the Latin probabilitas, which can also mean “probity” Chances of occurrences lies between two things possible and impossible Introduction The probability and combinatorics have common origins. It was first developed when gambling games were analysed more than 300 years ago. While probability theory has […]
A Venn diagram is a diagram that shows all possible logical relations between a finite collection of different sets Introduction Venn charts, named after the English mathematician John Venn, which introduced their use in 1881, Venn diagram can be used to represent sets graphically. In Venn diagrams the universal set U which contains all the subjects that are shown as a […]
