What is mathematics?

The students of mathematics may wonder where the word "mathematics "comes from. Mathematics is a Greek word, and, by origin or etymologically, it means "something that must be learnt or understood", perhaps “acquired knowledge" or "knowledge acquirable by learning" or “general knowledge". The word "mathematics'' is a contraction of all these phrases. The celebrated Pythagorean school in ancient Greece had both regular and incidental members. The incidental members were called "auditors"; the regular members were named "mathematicians" as a general class and not because they specialized in mathematics; for them mathematics was a mental discipline of science of learning. What is ma­thematics in the modern sense of the term, its implications and connota­tions? There is no neat, simple, general and unique answer to this question.

Mathematics as a science, viewed as a whole, is a collection of branches. The largest branch is that which builds on the ordinary whole num­bers, fractions, and irrational numbers, or what, collectively, is called the real number system. Arithmetic, algebra, the study of functions, the cal­culus differential, equations, and various other subjects which follow the calculus in logical order, are all developments of the real number sys­tem. This part of mathematics is termed the mathematics of number. A second branch is geometry consisting of several geometries. Mathematics contains many more divisions. Each branch has the same logical structure: it begins with certain concepts, such as the whole numbers or integers in the mathematics of number, and such as point, line and tri­angle in geometry. These concepts must verify explicitly stated axioms. Some of the axioms of the mathematics of number are the associative, commutative, and distributive properties and the axioms about equalities. Some of the axioms of geometry are that two points determine a line, all right angles are equal, etc. From the concepts and axioms theorems are deduced. Hence, from the standpoint of structure, the concepts, axioms and theorems are the essential components of any compartment of ma­thematics. We must break down mathematics into separately taught sub­jects, but this compartmentalization taken as a necessity, must be com­pensated for as much as possible. Students must see the interrelation­ships of the various areas and the importance of mathematics for other domains. Knowledge is not additive but an organic whole and mathema­tics is an inseparable part of that whole. The full significance of mathe­matics can be seen and taught only in terms of its intimate relationships to other fields of knowledge. If mathematics is isolated-from other provinces, it loses importance.

Probability of occurence

In mathematical language the choice, the probability of success is the ratio of the number of ways in which the trial can succeed to the total number of ways in which the trial can result. Here nothing favors the choice of any particular circle; they are all on the same page, and you are just as likely to cover one as another. The trial can result in five ways; there are five black circles. The trial can result in nine ways; there are nine circles in all (in exercise 1.1). If p represents the probability of success, then p = ,5-9..

Similarly, the probability of failure is the ratio of the number of ways in which the trial can fail to the total number of ways in which it can result. If q represents the probability of failure, in this case q = ,4-9.. Notice that the sum of probability of success and failure is 1. If you put your finger on a circle, it is certain to be either a black circle or a white one, for no other kind of circle is present. Thus p+q = ,5-9.+,4-9.=1. The probability that an event will occur can not be more than 1. When p =1, success is a certainty. When q =1, failure is sure. Let S represent the number of ways in which a trial can succeed. And let f represent the number of ways in which a trial can fail.

𝑝=,𝑆-𝑆+𝑓.;𝑞=,𝑓-𝑆+𝑓.;𝑝+𝑞=,𝑆-𝑆+𝑓.+,𝑓-𝑆+𝑓.=1

When S is greater than f, the odds are S to f in favor of success, thus the odds in favor of covering a black circle are 5 to 4. Similarly, when f is greater than S, the odds are f to S against success. And when S and f are equal, the chances are even; success and failure are equally likely. Tossing a coin illustrates a case in which S and f are equal. There are two sides to a coin, and there is no reason why a normal coin should fall one side up rather than the other. So if you toss a coin and call heads, the probability that it will fall heads is ,1-2.. Suppose you toss a coin a hundred times, for each of the hundred trials, the probability that the coin will come down heads is ,1-2.. You might expect fifty of the tosses to be heads. Of course, you may not get fifty heads.But the more times you toss a coin, the closer you come to the realization of what youexpect.

If p is the probability of success on one trial, and K is the number of trials, then the expected number is K p. Mathematical expectation in this case is defined as K p.

a. What does the article deal with?

b. If you were shown 9 red circles and 6 black circles and were asked to choose one

c. Can you give the definition of the probability of failure? What is it?

d. What are the odds in case f > S?

e. What are the odds in case f < S?

b. The sum of the probability of success and failure is equal to 1.

c. The probability that an event will occur can be more than 1.
