Probability is a fascinating math concept. It can be applied in many aspects of our students’ daily lives. As the world of technology continues to grow, teaching of many math concepts can be done in the classroom and reinforced by math learning websites. The coin flip and roll dice games that we looked at are a nice tool to show our students the concept of probability in visual form.

The coin flip game showed the probability of two results either heads or tails. It is less complex because it only has two possible results, the probability of a heads or tails coming up when flipped is 50% or one out of two chance. In the game, you control the number of flips of the coin and the results are noted and percentage is giving to you. In my results of 20 single flips, the results were 50% heads and 50% tails. But when I used the auto flip button for another 20,000 flips, the results were 50.11% heads and 49.89% tails. There was a historical button which shows historical data with results of 50% heads and 50% tails. It is a nice visual tool to explain the results of the probability concept.

The dice roll game showed the probability with many more results. It is more complex. It can give the results for one die, which are six possible results, two dice, which are 11 possible results, and three dice, which are 16 possible results. When you are rolling one die, you have a 16.67% or a 1 in 6 chance for each number to come out. When you add die to the dice roll game the results of your rolls are weighted according to the number of possible results that the dice could give. For example in order to roll a two with two dice, there is a 2.78% or 1 in 36...

Rolling Dice
Statistics is based upon based upon common sense and logic, in a complex data. Probability is just one of the many topics in statistical mathematics. It is used in our daily life, all over the world. Even games, require taking a chance and using probability to determine the predicted outcomes.
Probability is the measure of how often a particular event will happen if something is done repeatedly, (596 Webster’s Dictionary). You cannot determine any events that will happen in the future, because there is always a chance that something odd will happen, (Linn 39-40).
Probability originally started for the purpose and attempt to analyze games of chance. Probability is also used in determining the outcomes of an experiment. Sample space is the collection of all results. Probability is a way to assign every event a value between zero and one.
What is the probability of rolling a pair of dice, or a deck of cards, or a jar of marbles? What is the probability of conceiving a boy or a girl? Many more are determined by the usage of the probability method.
Probability is used to represent the likelihood that odds of winning a random drawing chance of rolling a seven when rolling two dice.

a) History of Probability
The scientific study of probability is a modern development. Gambling shows that there has been an interest in quantifying the ideas of probability for millennia, but exact mathematical descriptions of use in those problems only arose much later.
According to Richard Jeffrey, "Before the middle of the seventeenth century, the term 'probable' (Latin probabilis) meant approvable, and was applied in that sense, univocally, to opinion and to action. A probable action or opinion was one such as sensible people would undertake or hold, in the circumstances. However, in legal contexts especially, 'probable' could also apply to propositions for which there was good evidence.
Aside from some elementary considerations made by Girolamo Cardano in the 16th century, the doctrine of probabilities dates to the correspondence of Pierre de Fermat and Blaise Pascal (1654). Christiaan Huygens (1657) gave the earliest known scientific treatment of the subject. Jakob Bernoulli's Ars Conjectandi (posthumous, 1713) and Abraham de Moivre's Doctrine of Chances (1718) treated the subject as a branch of...

ANALYSIS
Physics has a lot of topics to cover. In the previous experiments, we discussed Forces, Kinematics, and Motions. In this experiment, the focus is all about Friction. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction like fluid friction which describes the friction between layers of a viscous fluid that are moving relative to each other; dry friction which resists relative lateral motion of two solid surfaces in contact and is subdivided into static friction between non-moving surfaces, and kinetic friction between moving surfaces; lubricated friction which is a case of fluid friction where a fluid separates two solid surfaces; skin friction which is a component of drag, the force resisting the motion of a fluid across the surface of a body; internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation and sliding friction.
When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Kinetic energy is converted to heat whenever motion with friction occurs, for example when a viscous fluid is stirred. Another important consequence of many types of friction can be wear,...

The case between Beauty and Stylish involves concept of a valid contract, pre-contractual statements, express term and misrepresentation.
A valid contract is established between Beauty and Stylish when an offer is accepted and there is intention for both parties to create legal relations. An offer refers to the expression of willingness of the offerer to be contractually bound by an agreement if his or her offer is properly accepted. It has to be clear and certain in terms. It must also be communicated to the offeree before it is being accepted. In addition, the acceptance has to be unqualified, unconditional and made by a positive act. In the case of Beauty and Stylish, a positive act refers to the signing of the contract. All terms of the offer must be accepted without any changes and cannot be subjected to any condition, taking effect only upon fulfillment of that condition. When Beauty and Stylish enter into the agreement, they must intend to bind and bound legally to each other by their agreement. This is the intention to create legal relations between two parties. In the meanwhile, this contract must possess consideration. A contract must therefore be a two-sided affair, with each side providing or promising to provide something of value in exchange for what the other is to provide.
Every contract, whether oral or written, contain terms. The terms of a contract set out the rights and duties of the parties. Terms are the promises and undertakings given by each...

THE DICE GAME
Introduction-
In the real world events cannot be predicted with total certainty. The best way in which we can do this is by saying that how likely is an event to happen, using the idea of probability.
Probability is the branch of mathematics, which studies the possible outcomes of given events together with the outcomes it also studies the' relative likelihoods and distributions. In Lehman terms, the word "probability” means the chance that a particular event {or set of events) will occur expressed on a linear scale from 0 {impossibility) to 1 {certainty), also expressed as a percentage between 0 and 100%.
Considering a game with two players, Ann and Bob. Ann has a red die and Bob a white die. They roll their dice and note the number on the upper face. Ann wins if her score is higher than Bob’s and Bob wins if the scores are the same.
This can be summarized as follows:
Number of Ann is greater than the number of Bob = Ann wins
Number of Ann is less than equal to number of Bob = Bob wins
Now considering the probabilities if both players roll their dice once each. To find the probabilities of both plays we can use a probability tree diagram, which is shown below:

... Homework #4 - SQL
Use the following (denormalized) database schema (and the attached tables) to write the queries.
Publishers (custid, name, city, phone, creditcode)
Bookjobs (jobid, custid, jobdate, descr, jobtype)
POS (jobid, poid, podate, vendorid)
Items (itemid, descr, onhand, price)
Po_Items (jobid, poid, itemid, quantity)
For each question, turn in the Oracle SQL query and the output. You should feel free to do these by hand (paper and pencil), or you may actually run them. I have created the tables and granted everyone in the class access to them. I would urge you to FIRST write them on paper, and THEN run them – just to be sure you understand them. You will not have access to Oracle SQL during the final exam. These take time, so please start early.
I have granted you all access to query the tables in my account. You can access them by typing suebrown., so to access the publishers table, type suebrown.publishers. As a second alternative, you can use the scripts in blackboard to create the tables in your own oracle space. It is your choice how you want to do this – just make sure that if you create the tables in your own directory that you do not change the data.
[6 pts] 1. How many different jobs are listed in the POS table?
[8 pts] 2. How many publishers fall into each of the three credit codes?
[10 pts] 3. List the jobid, podate, custid, and name for any jobs with purchase orders dated (podate) since February 1, 2006....

...• What were the most revolutionary social and economic developments of the last quarter of the nineteenth century?
• How did different groups of Americans respond to those changes and how effective were their responses?
• What role did government play in these developments?
In the late 1900s some of the most social and economic developments were railroads, steel oil, the type writer cash register, light bulb and agriculture. The development of the railroad made it easier for immigrant to come to this country for work. This meant that there were more group of different races and cultures in America. And in some states there became an over population and city workers like police and garbage men could not keep up with the demand of so many people. Some groups mover to open land for the Homestead Act. They had hope of farming and staying on the land for at least five years as agreed but the supply and demand of agriculture did sustain so many farmer moved off the land well before their five years. The government played many different role I deescalating some issues in American history. Women and children were being worked for long hours and getting paid a little bit of nothing in return for their hard work. So the government put labor laws into place that were to protect women and children. As oil, steel and railroad industries grew so did the levels of pollution. The government again put laws that were to protect animals and the earth so that there would not...
