Summary - A well-defined collection of definite objects is called a set. In roster method of representing a set, all the elements are listed in the set. In property method of representing a set, all the elements are represented by stating all the properties w..

Pure substances are made up of only one type of constituent particles. They are homogenous and have a definite set of properties characteristic of themselve..

Let X be a set of numbers and f : N n --> X be a function, then the ordered set {f(1), f(2),...., f(n)} is called a finite sequence in X...

A Boolean algebra is a set B with two distinct elements, along with the binary operations '+' and '.' and a unary operation (') which satisfy closure property, commutative property, existence of unit element, distributive property for both the binary operation..

1. Sample space: Set of all possible outcomes of a random experiment. 2. Event : An event of a random experiment is defined as a subset of the sample space. 3. Exhaustive outcomes: All the outcomes of a random experiment. 4. Random variable: A real valued function ..

Pure substances are made up of only one type of constituent particles. They are homogenous and have a definite set of properties characteristic of themselves. An element is a pure substance that is made up of only one kind of atoms. An atom is the smallest particle of an element, ..

All vibrating and oscillating bodies are described by the length of time required for one complete cycle. Time period (T) is the reciprocal of frequency (f). Vibrations and oscillations are also characterised by terms like amplitude of vibrations which is actually the maximum distance the ..

Biotechnology is the use of technological procedures in the field of biology for obtaining products of commercial importance. Biotechnology is the use of technological procedures in the field of biology for obtaining products of commercial importance. Biotechnology has two main aspects gene..

>Cardiac cycle consists of events in the heart repeated cyclically during each heartbeat. Contraction and relaxation of cardiac chambers are respectively called systole and diastole. The heart beat results from a wave of electrical potential called cardiac impulse spreading over the cardiac chamber..

(i) Let X be a set of numbers and f : N n X be a function, then the ordered set {f(1), f(2),...., f(n)} is called a finite sequence in X. (ii) Let X be a set of numbers and f : N X be a function, then the ordered set {f(1), f(2),....} is called ..
