Three times each day, a quality engineer samples a component from a recently manufactured batch and tests it. Each part is classified as conforming (suitable for its intended use), downgraded (unsuitable for the intended purpose but usable for another purpose), or scrap (not usable). An experiment consists of recording the categories of the three parts tested in a particular day. a) List the 27 outcomes in the sample space. b) Let A be the event that all the parts fall into the same category. List the outcomes in A. c) Let B be the event that there is one part in each category. List the outcomes in B. d) Let C be the event that at least two parts are conforming. List the outcomes in C. e) List the outcomes in A ∩ C. f) List the outcomes in A ∪ B. g) List the outcomes in A ∩ Cc. h) List the outcomes in Ac ∩ C. i) Are events A and C mutually exclusive? Explain. j) Are events B and C mutually exclusive? Explain.
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.
