HOW TO USE THE THEORY OF ATTRIBUTES IN PROBABILITY

My intention is not to prove anything right or wrong,but as a student it is just a piece of my thinking compiled with little research. This is an article establish the relationship between the use of theory of attributes and probability.

There are two types of characteristics, one is quantitative like height, weight,price,etc. which can be measured cardinally,that is,numerically.The other type of characteristics is qualitative characteristics like honest,hardworking,etc.which cannot be measured cardinally. Theory of attributes tries to explain the inter-relation between the attributes,its consistency,whether the given data is true of false,etc. TO KNOW MORE..........

Probability is the chances or possibilities of occurence of event. Probability theory helps us to find the probabilities of various events.

INTER-RELATION:

You can use the theory of attributes in probability.
In the case of two objects,use the nine square table in which, A should be probability of occurence of first event and so opposite is alpha. B should be probability of occurence of second event.
AB is probability of occurence of both events.
and so on...

For occurence of three events you can use the contingency table for three attriibutes.

...chapter, you will be able to ONEDefine probability. TWO Describe the classical, empirical, and subjective approaches to probability. THREEUnderstand the terms experiment, event, outcome, permutation, and combination. FOURDefine the terms conditional probability and joint probability. FIVE Calculate probabilities applying the rules of addition and multiplication. SIXUse a tree diagram to organize and computeprobabilities. SEVEN Calculate a probability using Bayes theorem. What is probability There is really no answer to this question. Some people think of it as limiting frequency. That is, to say that the probability of getting heads when a coin is tossed means that, if the coin is tossed many times, it is likely to come down heads about half the time. But if you toss a coin 1000 times, you are not likely to get exactly 500 heads. You wouldnt be surprised to get only 495. But what about 450, or 100 Some people would say that you can work out probability by physical arguments, like the one we used for a fair coin. But this argument doesnt work in all cases, and it doesnt explain what probability means. Some people say it is subjective. You say that the probability of heads in a coin toss is 12 because you have no reason for thinking either heads or tails more likely you might change your view if you knew...

B) the variable for which an algebraic equation is solved.
C) a numerical measure of a probability experiment.. Ans = C
D) a qualitative attribute of a population.
4) Given the table of probabilities for the random variable x, does this form a probability distribution? Answer yes or no.

...I. ProbabilityTheory
* A branch of mathematics concerned with the analysis of random phenomena. The outcome of a random event cannot be determined before it occurs, but it may be any one of several possible outcomes. The actual outcome is considered to be determined by chance.
* The word probability has several meanings in ordinary conversation. Two of these are particularly important for the development and applications of the mathematical theory of probability. One is the interpretation of probabilities as relative frequencies, for which simple games involving coins, cards, dice, and roulette wheels provide examples.
* It is the likeliness of an event happening based on all the possible outcomes. The ratio for the probability of an event 'P' occurring is P (event) = number of favorable outcomes divided by number of possible outcomes.
Example:
A coin is tossed on a standard 8×8 chessboard.
What is the theoretical probability that the coin lands on a black square?
Choices:
A. 0.5
B. 0.25
C. 0.42
D. 0.6
Correct answer: A
Solution:
Step 1: Theoretical probability = number of favorable outcomes / number of possible outcomes.

...A theory is a vital basis of every nursing endeavor. It can possibly explain the sense of every nursing action in the field. Without such, the practice of the profession will lack sense and deeper meaning. All throughout the history of nursing, it became a foundation that governs nurses in performing their duties. Like the theory of Nightingale which guided nurses during the Crimean War when Florence, along with other trained nurses took care of the soldiers who were injured by attending to their needs of cleanliness as to prevent infection which was rampant during that period. This theory had been evident in the day-to-day nursing practice. The most obvious way that nurses perform to apply the said theory is handwashing. It was proven through studies that frequent handwashing greatly helps in the prevention of infection which strengthens the credibility of Nightingale's theory. In view of this, I can say that nursing theories are not just mere sources of principles behind phenomena in nursing practice but above all, they are fundamental rudiments of uplifting the motivation of nurses to do their functions. If nurses had a better view of these theories, it would not be hard for them to do a nursing intervention for they know the benefits of such as supported by the concepts and principles embedded in those theories.

What is Information?
Information is a fact provided or learned about something or someone. Organisations can use information to work more effectively. There are many different types of information that organisations can use. These are qualitative information, quantitative information, primary information and secondary information.
Qualitative
Qualitative information is non-numeric information that is based on opinions. It is often word based and can’t be measured. An example of this would be if you were trying a drink, you would describe the taste of the drink and say if it is good or bad. This information is based on your opinion. Qualitative information is useful for a business because it gives them more detailed feedback. However, this feedback would take a long time to process.
Quantitative
Quantitative information is information that can be seen as factual information and is not...

...ProbabilityTheory and Game of Chance
Jingjing Xu
April 24, 2012
I. INTRODUCTION
Probabilitytheory is the mathematical foundation of statistics, and it can be applied to many areas requiring large data analysis. Curiously, that the study on probabilitytheory has its root in parlor games and gambling. In 17th century, dice gambling was a very common entertainment among the upper class. An Italian mathematician and gambler Gerolamo Cardano founded the concept of probability by studying the rules of rolling dice: since a die is a cube with each of its six faces showing a different number from 1 to 6, when it is rolled, the probability of seeing each number is equal. Therefore, some of the gamblers began to wonder, that taking a pair of dice and rolling them a couple of times, which has the larger probability of seeing a sum of 9 or seeing a sum of 10? What about seeing double sixes? In a correspondence between Blaise Pascal and Pierre Fermat, the problems were resolved, and this triggered the first theorem in the modern theory of probability.
