Free Essays on Probability to Get Inspired & Learn by Example

Probability is used to define the process of quantifying the likelihood of an event occurring. An event defines the results of an experiment. Probability is computed by dividing the number of count of an event occurring divided by the total possible outcomes.
A is the event of the episode containing sexual behavior is 338. The total number of episodes is 959. P (A) is obtained to be 0.352.

Question (b)

C defines the event that the episode is a comedy. The total number of episodes that are in the category comedy is 195. The total number of episodes in the experiment Continue reading...

Clinical scenario:
A 62 year old Scandinavian man arrives in the emergency department of AZMC in Maastricht, complaining of pain in his right leg and palpitations. He tells me that he has just arrived on an especially cramped flight from Riyadh, Saudi Arabia where he could not move his legs. During the flight, he felt a pain in his right leg which he attributed to a muscle cramp. After landing, he noticed that the pain would not Continue reading...

Introduction

This paper is intended to explain the math of probability in the most popular at present varieties of poker - Texas Hold'em. Mathematics in poker is fairly simple and does not require deep knowledge in this field for successful application in practice. However, the basic knowledge of statistics and probability theory is necessary.
In Texas Hold'em, it is very important to know a type and a number of possible combinations of starting hands with whom or against whom you have to play. Playing poker, you have to anticipate, which possible hands could go against you opponent and from your Continue reading...

Concept
The concept behind estimating project times is the understanding that the possible durations for a project to be completed form a normal distribution. The variance of the project is the square of the standard deviation of the time taken for the project. Once the standard deviation is obtained, the Z Score (the standard normal variate) can be obtained, from where the probability of completion of project in a given time can be derived using the normsdist function in Excel (Countryman, 2013).

Problem

For the given problem, Tcp = expected project time as per critical path = 21 months.
Project variance = σt2 = Continue reading...

Introduction

In the last decades, there has been a lot of discussion about the glass ceiling, or whether there is any difference in career opportunities between men and women. All across the world, women tend to have a smaller chance of success on the labour market, as well as a lower chance of becoming an entrepreneur successfully. A lot of research has been conducted concerning this subject (e.g., Verheul, Van Stel, & Thurik, 2006), but only a small part of this research has focused on the differences within this large pool of female entrepreneurs and nascent female entrepreneurs globally.
The process Continue reading...

PASCAL WAGER

What is Pascal Wager? Describe and critically analyze that argument for the belief of God.
Pascal Wager is an argumentative philosophy on the existing and non-existence of God. Blaise Pascal (1623-1662) did it and he was trying to show that there was no need of not believing the existence of God since the rewards were more serious than in not believing. Pascal used this as an apologetic method in a form of a wager to convince the atheists and agnostics that God exists and there is heaven and hell. It is an appeal to the atheists’ chief god who Continue reading...

Introduction

In this paper we use the knowledge of probability and conditional probability to examine the effectiveness of the judges and courts given in a data sample. The data represents the results of the judges decisions – how many were disposed, how many were appealed and if appealed, what is the amount of the reversed cases.

Body

We are given with the data of 16 judges of Common Pleas Court (43945 cases), 4 judges of Domestic Relations Court (30499 cases) and 20 Municipal Judges (108464 cases). There are 182,908 cases in total.

For each judge there is following information given:

Disposed – the number of disposed cases
Appealed – the number Continue reading...

Interpreting Logistic Regression Output from Excel

Interpreting Logistic Regression Output from Excel

Introduction

When we have a binary output variable Y, and we wish to model the conditional probability of (Y, given X) as a function of X, one approach is to perform logistic regression. Logistic regression introduces the ‘logistic transformation’, log p (x)/(1-p (x). This logistic transformation helps in avoiding results that would not normally make sense. Using this approach, logistic regression helps to determine the probability of a categorical dependent variable based on one or more predictor variables (Carnegie Mellon University, n.d.).
The challenge is to convert this data to a prediction Continue reading...

Abstract

Hand Hygiene (HH) or hand washing in hospital must improve in order to reach zero mortality, shorter patient stays and lower costs for patients and their families. A meta-analysis was carried out to collect studies with a common methodology so that the results can be evaluated with statistical analysis. Searches on the PubMed database were used to identify articles addressing both the issue of hand hygiene and paediatric hospitals. Several searches were carried out until the number of articles for the study was narrowed down to five peer-reviewed academic articles. The number of total HH opportunities and positive Continue reading...

Descriptive statistical procedure is a form of presenting numerical facts and data in either tabulated or graphical form, it does not involve making conclusions beyond the analysis. Inferential statistical method involves taking representative samples from a population, analyzing the sample and making generalized inferences for the whole population. Inferential methods of data analysis include hypothesis testing where statistician test a proposed theory based on collected data (Al-Benna, 2010). Other inferential analyzes are correlation testing and regression analysis. The following information has its basis in a case study of products marketing business, where the researchers used descriptive and inferential methods Continue reading...
