The Use of **Probability** in Inferential Statistics
Statistics use assumption on population distribution to estimate population values based on sample values (Kemp & Kemp 257-66). **Probability** distributions functions or simply distribution functions are used (Soong 39-41). The distribution function associates a variable value with a **probability** (Soong 39). This can take the form Fx(x) =P(Xx) where the lowercase x refers to a specific value of a variable. **Probability** distribution functions have shapes represented by the mathematical equations. The areas under the curves or distribution functions are associated with **probabilities**.
In business statistics, some of the distribution functions that are often used are the Z-statistics, t-statistics...

.... It means that is there is nothing certain and exact associated with an event, and that happenings are uncertain and there are **probabilities** that are associated with them. **Probability** can be defined as the study that is concerned with locating certainty in uncertain events. **Probability** is known as the method of weighing evidence and opinion about uncertain and complex environment. Christiaan Huygens is supposed to be the first person to treat **probability** with scientific principles to provide a more refined form of the term in the year of 1657. There are several functions of **probabilities**. Distributions are considered one of them. These functions are used to assign the possible and **probable** events to the entire series of the events...

...= the possibility 6/48, 7/48
After showing of the cards, the following are the **probability**= 6 diamonds occurring= 6/48
= 3 diamonds occurring= 3/48
7 diamonds occurring= 7/48
From this calculation, there is little possibility, (3 of 52,) of three coming up again. **Probability** also do not repeat itself and therefore the **probability** of three coming up again is still little if reasoning from the same line of thought. This therefore supported my need to continue playing because I knew my down cards could come up instead of the three of diamonds.

...TWE <**Probability** Techniques> and Section # of Advantages of **Probability** **Probability** is often used to portray an approach of mind towards some attitude of mind towards some scheme of whose actual truth we are not sure of (Stuart, 2009). In simple words it can be defined as the chance of any occurrence happening. The importance of **probability** can be seen in our everyday life, even though we don’t, at times appreciate its applicability but it is always there around the corner, waiting for us to utilize it. The use of **probability** has really helped me as the head basket ball coach of an upper league division. The use of **probability** was introduced to me by my assistant coach who explained how I can use the magic of simple math to predict...

... A 7-card hand is chosen from a standard 52-card deck. a. How many of these will have four spades and three hearts?
Number of ways to pick four spades = 13 C 4 = 715
Number of ways to pick three hearts = 13 C 3 = 286
Therefore, there would be [13 C 4 * 13 C 3] = 204,490
b. What is the **probability** that we draw a hand composed of precisely four spades and three
hearts?
Number of ways to pick 7 cards randomly: 52 C 7 = 133,784,560
Therefore, **probability** = [13 C 4 * 13 C 3] / (52 C 7) = 0.001528

...of eleven heads and nine tails. Although flipping a coin is said to have an equal chance of coming up on either side, one’s experience did not have such a result. This may be due to the fact that the experiment was only made twenty times. According to frequentists, “the **probability** of getting a heads is 1/2, not because there are two equally likely outcomes but because repeated series of large numbers of trials demonstrate that the empirical frequency converges to the limit 1/2 as the number of trials goes to infinity” (Edurite.com, n.d.).
` When one played the dice roll, one realized that the outcomes are much more than the coin flip because each die has six sides. The other die has also six sides; thus, rolling the...

...in **probability** sampling. The outcomes of **probability** sampling are more likely to give a fairly accurate representation or reflection of the entire population. It is imperative that researchers consider the availability, time, cost, and the subject to research about when choosing a sampling technique (Rubin & Babbie 2011, pg12). **Probability** sampling has gained vast popularity among scholars in both fields of quantitative and qualitative study. Overall, researchers or project managers would employ non-**probability** in the survey while holding on to a basic assumption that the entire population has evenly distributed characteristics.

...in a logical decision making process. Uncertainty which means knowing just a little of what might **probably** happen triggers much wider and deeper understanding of the value of numbers among those concerned individuals who are trying to make certain decisions. For instance, computation of **probabilities** based on the actual random samples from an entire class or population can be viewed much of a representation. This can be meaningful knowing the fact that drawing a sample from a certain population in which every entity has equal chance of being drawn can be viewed reliable in explaining the entire sample.
In this paper, I gave light on the value of **probability** which will fall to what...

..., the chi-square statistics are used for inferential statistics related to correlations and associations. These are only some of the distributions but they indicate nevertheless the value of **probability** distribution for inferences in statistics.
I. Introduction
In making inferences on the population based on sample characteristics, man used **probability** distribution or **probability** density functions (McClave et al. 172-173; Schaum 55). **Probability** distributions or density functions associates a numeral to a **probability** value. **Probability** density functions are curves represented by mathematical equations that best capture the characteristics of the curve. In turn, the curves or the areas under the curve are associated with **probability** level...

..., man uses **probability** distribution functions that express a set of assumptions on how variable values are **probably** or possibly distributed across a population. The assumptions help man to make inferences on the population based on sample characteristics. The assumptions or the **probability** distribution functions allow man to associate variable values with **probabilities**. In other words, inferences on population characteristics associate or attach **probabilities** with regard to variable values in the population using certain assumptions (or which amount to the same thing: the use of a specific **probability** distribution function).
At the same time, there is a class of statistics known as nonparametric statistics. Nonparametric statistics makes...

.... For this the managers of business need to take informed decisions and the information has to be derived from nowhere but from the data relevant to the business. It is here that statistics and **probability** comes to help them. Statistics is the branch of knowledge that processes data to discern hidden information, reveal patterns and extract executable results [1]. One can get lot of information by simply arranging data in frequency and relative frequency tables [2]. One can get a good idea of central tendency and dispersion of the data set. The organized dataset can also be represented pictorially as histograms, line charts etc. It is said that a picture is worth thousand words. This is because; even a person with common sense can see...

Introduction and background information
Developments in information technology has changed means of communication and led to a shift from traditional communication media to information technology based approaches. Mass communication for instance initially involved a prior announcement for awareness among the target audience or the use of media such as televisions, radios and the print media that had their own limitations. The social media has however developed to replace the originally used communication methods. The avenue that connects people across different barriers such as age and geographical boundaries is the most contemporary means of communication as is identified by its many followers. Examples of social...

.... It is played with a deck of fifty two cards. The ranks of a player’s cards and the combinations of these cards help determine the winner. In order to win big, players risk larger sums of money, hoping that they do not lose. Therefore, poker, just like any other gambling activity, is purely based on chance. In mathematics, one of the widely covered topics is **probability**, which is the study of the likelihood of an event occurring. For this reason, poker is directly related to this mathematical concept because outcomes are based on chance. Although most people question the importance of studying mathematics in school, the application of mathematical concepts in the real world are varied. **Probability**, which...
