information tutor: Expected value is the main thought in probability, in an intellect more general than probability itself. The expected value of a real-valued selection variable offers a compute of the center of the distribution of the variable. More considerably, by taking the expected value of various functions of a common random variable, we can calculate a lot of interesting features of its distribution, including spread and correlation. Tutor is a personality working in the education of others, either
this topic we will discuss about solving expected value x for discrete chance variable. Expected value is one of the fundamental thoughts in probability, in a sense more general than probability itself. The expected value of a real-valued chance variable offers a compute of the center of the distribution of the variable. More significantly, by taking the expected value of a variety of functions of a general random variable, we can work out a lot of interesting features of its distribution, including

the customers served instantaneously on the arrival and there will be no queue. If the number of services is finite, then the customers are served according to the specific order. Further the customer may be served in batches of fixed size or of variable size rather than individually by the same server, such as computer with parallel processing of people boarding in a bus. The service system in this case is termed as bulk service. 1.4 QUEUE DISCIPLINE Queue Discipline refers to the rule by which
The Kelly Criterion or sometimes called a Kelly bet is a formula used to decide the optimal sized stake of the bank to bet on a certain outcome. The way the Kelly Criterion works is that if one believes to have an edge over the bookmakers odds for a certain outcome one applies the kelly formula to calculate how much of their bank to stake and then do this for a series of bets resulting in a profit. Many argue the Kelly strategy is the strongest strategy among all betting strategies in the long term
Risk is an integral part of everyday human life. We both seek, and are unwillingly exposed to varying degrees of risk. Risk can be defined as being a situation with more than one outcome. Risk should be quantifiable, in that, that the risk taker should have an idea of the probabilities of the possible outcomes occurring. For Example, investing in a stock. Investing in a stock can give the investor multiple outcomes, it can give a negative outcome, like when the stock performs badly in the market
Abstract — Partially Observable Markov Decision Processes (POMDP) has been widely applied in fields including robot navigation, machine maintenance, marketing, Medical Diagnosis, and so on [1]. But its exact solution is inefficient in both space and time. This paper investigates Smooth Partially Observable Value Approximation (SPOVA) [2], which approximates belief values by a differentiable function and then use gradient descent to update belief values. This POMDP approximation algorithm is applied
The biggest topic of this podcast was the gambler’s fallacy which is the notion that random events alternate. An example is a coin toss to decide. This is used to decide many things to include who gets the ball first during a National Football League game. Coin tosses gives the illusion that there is a fifty-fifty chance of landing on either heads or tails because there are only two sides to the coin when in fact, the coin could land on heads more times than tails, and vice versa.

Statement of the Problem. Many of Merck’s most popular drugs, VasotecTM, MevacorTM, PrinivilTM, and PepcidTM are approaching their patent expiration date; these drugs have generated $5.7B in Merck’s worldwide sales. It is expected that sales of these products will drop precipitously as generic substitutes become available after patent expiration. Merck has an opportunity with LAB Pharmaceuticals to license Davanrik which is currently in pre-clinical development and was originally developed to treat
Enhancing Group Performance Organisational psychologists have been interested in seeing whether random selection of leaders or the usual systematic selection of leaders leads to greater task performance and greater group cohesiveness (also known as group maintenance). Finding significant results here would be beneficial in the workplace if the problem of random selection vs. formal selection is solved as it would help increase group harmony and productivity. The findings of previous research
data. Data Collection: I choose to collect my leaves from a tree in my back garden, as it was easy to access. I picked the leaves from different places and different heights around the tree so that my sample of leaves would be random. I choose a sample size of 35 leaves because it is large enough to reflect the trend amongst the width and length of the leaves on the tree, but still keeping it to a manageable size. When I collected 35 leaves I measured the length of
A Random Walk Down Wall Street There is a sense of complexity today that has led many to believe the individual investor has little chance of competing with professional brokers and investment firms. However, Malkiel states this is a major misconception as he explains in his book “A Random Walk Down Wall Street”. What does a random walk mean? The random walk means in terms of the stock market that, “short term changes in stock prices cannot be predicted”. So how does a rational investor determine
observations were random samples of twenty-five various employees divided into two distinct, independent populations, smokers and non-smokers. Then data on their absences from work for the previous year were obtained and used in this statistical inference. Because of a strong association between smoking and ill-health, it is generally accepted that smokers miss more work than their non-smoking counterparts. Does the smoker miss more work than the non-smoker? Data from these random samples were used
long as a month, with one game every day, eight hours each. Over 120 countries officially consider chess a sport. The Unites States is not one of them. That may be because we seem to have a very narrow-minded view of what exactly a sport is. Ask any random person if chess should be considered a sport, and the most likely response will be hysterical laughter, yet more people play chess competitively than any other game in the world, and more books have been published on chess than any other subject.
This study used content analysis to identify dominant AIDS-HIV themes in the manifest news content of AP, Reuters, AFP, ITAR-TASS, and IPS. A systematic random sample of AIDS-HIV stories disseminated by the five wire services between May 1991 and May 1997 (both months included) was obtained. This decade was selected because several empirical studies of coverage in the 1980s have been conducted; however, few studies examine the 1990s. The decision to examine the print news media was driven by the
Androcentrism When I started to think about what to write for this paper I wanted to learn more about androcentrism. Well, I guess I know what it means, but I wanted to see what it means to other people. In Random House Webster’s Unabridged Dictionary 2nd Edition the definition for androcentric is centered on emphasizing, or dominated by males or masculine interests. Then I went online and mostly the same definition. The only definition that I found that said anything about women was at http://dictionary
Niches of the Mind;The Brain and Language As the story goes, creation is characterized by expansion and contraction, disorder and order, random change and selection. It is observed in evolution how random change and disorder have brought about, from the scraps floating in a puddle on early earth, the fantastic diversity and incomprehensible complexity of life. The counterpart to this is death, making space for the new and guiding changes in the old through selection. What can this story tell
The Picture of Dorian Gray as a Moral Book The Picture of Dorian Gray was a remarkably well-written book due to the reaction of its themes by society. In the preface of the novel, Wilde introduces the opinion that "...there is no moral or immoral book. Books are well written or badly written. That is all." Numerous views can be taken upon this fastidious comment. Many would agree that Wilde is justifiably correct because the preface was written with the intention that his readers understand
energy, lots of short little fuses that were being burnt at intervals with no apparent rhythm. Even the way she spoke was joyfully random and unexpected. Instead of just standing up when she was called on, she would leap from her chair. The next energy we explored was vibratory. Vibratory is similar to percussive, but where as percussive is made up of seemingly random spurts of energy, vibratory is a constant flow of repetitive, rhythmic beats. Jeff was vibratory. His feet would tap the ground
