    entire populace like weight‚ gender‚ color‚ religion‚ job types‚ etc. Sample Data surveying is also extremely cost effective opposed to surveying an entire population. In short‚ this form of Sample Data is‚ from my own opinion‚ nothing more than probability theories. Population Data On the other hand‚ Population Data is just that; a means or census aimed at providing Data specifically based on the demographics‚ collective distinctiveness of a populace‚ individualism‚ and the primary starting point

    Probability refers to the likelihood or relative frequency for something to happen. Blaise Pascal is referred to as the father of probability. Pascal contributed to the branch of mathematics known as probability in 1653. Through his work in probability‚ Pascal invented the binomial coefficients which are now known as Pascal’s Triangle. Pascal’s major input to the philosophy of mathematics came with his “Of the Geometric Spirit””.1 Blaise Pascal was also a major contributor to the founding of Statistics

    reliability (probability of working). Assume components fail independently. What is the probability that the entire system works? (only write down the expression) P(works) = P(A)*P(B) + P(C)*P(D)*P(E) – P(A)*P(B)*P(C)*P(D)*P(E) = 0.7*0.7 + 0.8*0.8*0.8 – 0.7*0.7*0.8*0.8*0.8 2. Finish the following Bayes theorem (only the basic version‚ not with total probability rule): For two events A and B‚ with P(A) > 0 and P(B) > 0‚ P(A|B) = P(B|A) * P(A) / P(B) 3. The probability that a regularly

    analysis is an important component of engineering work that draws on the areas of probability and statistics. As the name suggests‚ reliability analysis is concerned with the investigation of the failure rates of components and systems‚ which are typically represented as probabilities. Life testing is a general term used to describe the experimentation and statistical analysis performed to investigate failure rates. Probability distributions that are used to model failure times are typically the exponential

    Page 4 :INTRODUCTION Definition: Probability is the study of chance or the likelihood of an event happening. Directly or indirectly‚ probability plays a role in all activities. Probability is a measure or estimation of how likely it is that something will happen or that a statement is true. Probabilities are given a value between 0 (0% chance or will not happen) and 1 (100% chance or will happen). The higher the degree of probability‚ the more likely the event is to happen‚ or‚ in a longer series

    The Chapter Five in "The Drunkard’s Walk" is "The Dueling Laws of Large and Small Numbers". At first‚ it discusses the problem about what is the connection between probability and observed results‚ however‚ true randomness does occur in nature. To learn more about the randomness‚ people found that nature’s perfect quantum dice. According to Benford’s law‚ numbers cumulative biased towards lower digits. This law can be used to identify fraud in dollar amounts. Then‚ the writer introduces two definitions
