The accompanying table shows the results from a test for a certain disease. Find the probability of selecting a subject with a negativenegative test result, given that the subject hashas the disease. What would be an unfavorable consequence of this error? The individual actually had the disease YesYes NoNo PositivePositive 330330 55 NegativeNegative 1515 11951195 The probability is nothing. (Round to three decimal places as needed.) What would be an unfavorable consequence of this error? A. The subject would experience needless stress and additional testing. B. The test would be shown to be not effective. C. The subject would not receive treatment and could spread the disease. D. The test would be shown to be not reliable.
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.
