Compound Probability

Compound probability can be defined as the probability of the two events which are independent. It can be defined as the multiplication of the probability of two events that are not dependent.

Tree diagram

Probability theory is a branch of mathematics that deals with the subject of probability. Although there are many different concepts of probability, probability theory expresses the definition mathematically through a series of axioms. Usually, these axioms express probability in terms of a probability space, which assigns a measure with values ranging from 0 to 1 to a set of outcomes known as the sample space. An event is a subset of these outcomes that is described.

Conditional Probability

By definition, the term probability is expressed as a part of mathematics where the chance of an event that may either occur or not is evaluated and expressed in numerical terms. The range of the value within which probability can be expressed is between 0 and 1. The higher the chance of an event occurring, the closer is its value to be 1. If the probability of an event is 1, it means that the event will happen under all considered circumstances. Similarly, if the probability is exactly 0, then no matter the situation, the event will never occur.

Question

Based on the following data, answer the following questions according to the stages of the solution. A pharmaceutical manufacturer claims that a drug produced by it has an efficacy of 90% 200 in reducing allergies for a period of 8 hours. In a sample of an allergic person, the drug relieved pain for 160 months. Is the manufacturer’s claim true at a level of 1% morale?

Researchers interested in lead exposure due to car exhaust sampled the blood of 52 police officers subjected to constant inhalation of automobile exhaust fumes while working traffic enforcement in a primarily urban environment. The blood samples of these officers had an average lead concentration of 124.32 µg/l and a SD of 37.74 µg/l; a previous study of individuals from a nearby suburb, with no history of exposure, found an average blood level concentration of 35 µg/l. Based on your preceding result, without performing a calculation, would a 99% confidence interval for the average blood concentration level of police officers contain 35 µg/l? Based on your preceding result, without performing a calculation, would a 99% confidence interval for this difference contain 0? Explain why or why not.

In Dr. Potter’s study of ‘Objective Increases in Fear Based on Type of Haunting’, he reported that ghosts earned a z-score of 0.93, spirits earned a z-score of -0.75, and phantoms earned a z-score of -1.18. Assuming that a z-score of 0.00 represents the average amount of fear a person experiences during a haunting, answer the following questions: Which of the hauntings tested would you select if you wanted to increase fear as much as possible? Why would you choose this haunting? Which of the hauntings would you give to someone if you wanted to decrease fear as much as possible? Why would you choose this haunting?
