person was found to have an HIV positive result. Therefore one naturally assumes the person has a 99% chance of having that disease; but this is wrong. If we then take a larger sample size, the number of possible false positives increase and the probability of that person having the disease also decrease. Here it is important to note that the test itself is accurate, but there is other outside relevant information needed to make the best and most accurate conclusion. The test gave a wrong positive

that are still appreciated today including a powerful influence on the development of modern economics, social science, and Pascal’s Theorem. Blaise Pascal is best known for his correspondence of 1654 with Fermat, which originated the theory of probability. He was also the author of ‘Traite du triangle arithmetique avec quelques autres petits traites sur lameme matiere’ written in 1654. He included in his treatise separate tracts describing the use of the Pascal’s triangle in the theory of figurate

Probability and Outcome A number of years ago in 1978 there was a movie that starred Warren Beatty. It was called Heaven Can Wait. Throughout the film, there was a common theme of probability and outcome. It kept showing how the probability of something happening seemed almost certain however; the outcome was different in many cases than one would have thought it to be.(Beatty, Beatty, & Henry, 1978) When I took my first statistics class, my professor on the first day asked a question of us all

the probability of the Gambler’s Fallacy. According to the Investopedia, “When an individual erroneously believes that the onset of a certain random event is less likely to happen following an event or a series of events. This line of thinking is incorrect because past events do not change the probability that certain events will occur in the future.” Gambler’s Fallacy is about our incorrect thinking of predicting what will happen next by the events happened before or the previous probability. For

Question 1 With the use of Merton Model, the probability of Default (PD) of each firm is summarized as follow: Company Name | ASX Code | Probability of Default | Adelaide Brighton Limited | ABC | 0% | Buderim Ginger Limited | BUG | 26.079% | FFI Holdings Limited | FFI | 0.056% | McPherson’s Limited | MCP | 0.003% | Reece Australia Limited | REH | 0% | Vietnam Industrial Investments Limited | VII | 2.472% | Question 2 Using 15 Sep 2008 as a cut-off point, the pre and post results

Mathematics, it is rare that a new branch of mathematics is introduced. That means that even branches of math that have been around for hundreds of years are still technically new, or at least relatively new. One such branch of mathematics is probability. Probability is only three hundred to four hundred years old, so it easily falls into this category when compared to branches of mathematics such as Geometry which dates back all the way to ancient Egypt in around 2900 BC, when it first became important

journal entry will define what non-probability sampling is and the different types such as snowball sampling, quota sampling, convenience sampling and purposive sampling. In addition, the pros and cons of non-probability will be discussed such as the correct sample size, determining the desired precision, and managing the variation in the population to name a few examples. Furthermore, this journal will discuss why a researcher might want to use non-probability sampling over other methods such as

The Probability of Life as an Argument for a Designer In response to the argument from life, Smith claims that “the argument from life again presents us with a false alternative between design and chance… in fact, there is neither; we have with life what we have with every other natural phenomenon: natural causes operating according to natural necessity” (270). Smith further claims that even if he concedes the improbability of life, that does not prove anything except “that an extraordinary occurrence

Chapter 3.1: History of Probability . Roulette Roulette is a game where a person plays not against another person but against a wheel. Roulette has thirty-eight compartments where 1-36 are numbered and are colored either black or red. The remaining two are numbered 0 and 00 and are colored green. People place their bets by placing their chips into their spots on the roulette table. Then the dealer spins the wheel and drops a ball onto that spinning wheel and then the ball stops in one of the

Probability of Divorce: Contrary to the reality in western industrialized nations, there is a common assumption that longer life-spans contribute to longer marriages. As the average length of marriage remains significantly the same, the reason for the end of marriage has changed from death to divorce. Actually, it's currently estimated that half of marriages in the United States will end either in separation or divorce before the 20th wedding anniversaries of the couples. The other half of these
