The Collier Encyclopedia’s definition for probability is the concern for events that are not certain and the reasonableness of one expectation over another. These expectations are usually based on some facts about past events or what is known as statistics. Collier describes statistics to be the science of the classification and manipulation of data in order to draw inferences. Inferences here can be read to mean expectations, leading to the conclusion that the two go hand in hand in accomplishing
of probability theory. Aided by the work of both Bradley Monton and Mark Colyvan, I will show why Collins’ argument fails. It can be shown that this line of reasoning concludes that the existence of a life permitting universe is zero. Essentially, Collins’ argument does not prove what he claims it does and is too strong to account for the existence of a life permitting universe because it not only misuses probability, but is rendered useless due to the paradoxes inherent in probability theory. Collins’
4. THEORITICAL BACKGROUND Since the originative works of Fama (1965 and 1970), where an efficient market from the informational execution point of view was defined as one where “stock prices ‘fully reflect’ all available information” (Fama 1970) and market efficiency was categorized into three levels: weak-form, semi-strong form and strong-form. First of all, the information set through weak form efficiency, reflects only the historical prices or returns. Second of all, the information set in semi-strong
In probability theory, The Birthday Paradox serves as a proposal that in a room of twenty-three people, there is a 50% chance that two or more people within that room share the same birthdate. The legendary source of this paradox claims to be discovered and first practiced by Richard von Mises, who posed the theory in 1939, However, the first practicing of The Birthday Paradox is, in all originality, Harold Davenport, who discovered this theory in 1927, making it the earliest discovery of this paradox
in order to set up and manage how their operations work. Mathematics can be used in accounting, managing inventory, marketing, sales, and financial gain. Typically in business one may use elementary arithmetic, elementary algebra, statistics and probability. In education, “Business Mathematics” undergraduates whom are business students take some mathematics classes. They are usually not as hard and might not go in detail as with other classes for example when the major is science. One usually studies
paper ... ...pothesis for an experiment or theory is reliant on semantics and thus syntax. The goal of significance testing is to reject the null hypothesis but not to disprove it. Significance Testing Significance testing is directly related to probability. Probabilities that reject the null hypothesis generally start at 0.05 and can approach 0 depending on the value that the researchers choose. The significance level (α) is the maximum probability value that rejects the null hypothesis. Statistical
five years? In this case, I try to analyze and see the probability of Best Restaurant expanding and getting more employees. This depended on many factors for example the financial factors, how the management team is organized and willingness to take risks. There are some indicators that will tell whether the organization will improve or not. For example, if the organization in this case Best Restaurant is financially stable then the probability of it improving is
“It's not your imagination. Those claw machines are rigged. But they're rigged in a surprisingly clever way — and not the way most people suspect.” In an analysis of claw machines and the probability of beating them, Phil Edwards introduces the idea that claw machines are designed to fail the player, but not in the way that many of those players assume. While most people believe that the toys are too small, or the claw is too slippery, the truth is that it is manipulated in an entirely different
Being Average Is it okay to be average? What does being average even mean? The Webster’s dictionary defines average as undistinguished and ordinary. Throughout my life I have always considered myself to be average, and I found out that it was not always the worst quality but it also was not the best quality to have. When I was a little kid, I never thought I was different from any of the other children. I knew I was not the smartest kid in my class or the fastest kid on the playground, but I was
a sequence of random variables known as time series (Markov chain). The values of variables change at the fixed points of the time. Continuous time stochastic processes are presented as a function whose values are random variables with certain probability distributions. The values of variables change continuously over time. Good examples of stochastic process among many are exchange rate and stock market fluctuations, blood pressure, temperature, Brownian motion, random walk. A Markov chain is a
d_ij=x_ij/(∑_(i=1)^m▒x_ij ) q_j (6) Where; x_ij is the value that corresponds measure of performance of the i -th alternative and j -th attribute and q_j represents the weight of ach attribute. d_ij represents dimensionless weighted value. The weights of attributes can be calculated using Equation (7). q_j= ∑_(i=1)^m▒d_ij (7) The alternatives are distinguished by beneficial (maximizing) attributes and cost (minimizing) attributes. 〖s+〗_i= ∑_(j=1)^n▒d_ij (8) 〖s-〗_i= ∑_(j=1)^n▒〖d_ij
successful or which author is good. Often we try and fight randomness in life based off of the human need to be in control. While we try and control life randomness comes in so many forms and manners from the butterfly effect to the large numbers theory the attempts to fight randomness often lead to more
works we have to go into detail that will include explaining: Probability Theory Converse Probability Birthday Paradox First we are going to talk about probability theory, which has to do with mathematics and analysis of random phenomena. You are probably used to putting the number of outcomes over the total amount of the object or total amount what you have. An example is, if you have a normal dice and you want the probability of rolling an odd number, you would take the total amount of odd
One of my favorite board games is Monopoly. I have noticed when I’ve played Monopoly that it seems like you always land on certain squares more than others. For instance, it seems like no one ever lands on Boardwalk, and players land on the pink and orange properties more often than they land on the others. The aim of this exploration is to find out if, over the course of a Monopoly game, a player will land on some squares more often than others and to use this information to figure out which properties

But these returns are uncertain which creates an element of risk for the investors. Nevertheless, investor is also interested in the total return and
also known as the birthday problem, these “chances” can be approximated. The birthday paradox helps calculate the probability that within n randomly chosen people, some pair will have the same birthday. According to the pigeonhole principle, which states that if m objects are placed into n number of containers, where m > n, at least one container will carry two objects; the probability that there will be at least one pair of people that have the same birthday, will be 100%, if there are 367 people
Differential reinforcement is defined as replacing a negative behavior with a positive behavior. Differential reinforcement also focuses on a specific behavior to address to create a specific positive reinforcer. With differential reinforcement, the positive behavior is the target behavior that will be recorded to determine the amount of positive outcomes. To record a differential reinforcer, the observer would record how many times the appropriate behavior occurred or when the negative behavior
are the only animals that reason, we do not follow probability theory, a normative model, very closely in our everyday reasoning. The conjunction fallacy is one of the major errors that humans commit when dealing with problems that involve probability. Exemplified by Linda the feminist bank teller, this problem occurs when we assume that a conjunction of two premises is more likely than one or more of the premises alone. According to probability, the conjunction of two premises can never be more
Debunking the Myth: The Human Trophic Level Kiana Kiser Mission Barbeque University Abstract This paper explores trophic levels and food chains to define the human trophic level (HTL). Using articles and studies based around the controversial debate of humans being top of the food chain, HTL was calculated and humans scored a 2.21 out of 5. This paper also clarifies what predators are at the top of the food chain and breaks down each trophic level and provides positions of specific organisms in
