Privacy Probability Unit 6 Problem: A spinner has 4 equal sectors colored yellow, blue, green and red. What are the chances of landing on blue after spinning the spinner? What are the chances of landing on red? Solution: The chances of landing on blue are 1 in 4, or one fourth. The chances of landing on red are 1 in 4, or one fourth. This problem asked us to find some probabilities involving a spinner. Let's look at some definitions and examples from the problem above. Definition Example An experiment is a situation involving chance or probability that leads to results called outcomes. In the problem above, the experiment is spinning the spinner. An outcome is the result of a single trial of an experiment. The possible outcomes are landing on yellow, blue, green or red. An event is one or more outcomes of an experiment. One event of this experiment is landing on blue.

In fact, there are two broad categories of probability interpretations , whose adherents possess different (and sometimes conflicting) views about the fundamental nature of probability: Frequentists talk about probabilities only when dealing with experiments that are random and well-defined . The probability of a random event denotes the relative frequency of occurrence of an experiment's outcome, when repeating the experiment. Frequentists consider probability to be the relative frequency "in the long run" of outcomes.

Probability theory From Wikipedia, the free encyclopedia Jump to: navigation search This article needs additional citations for verification Please help improve this article by adding reliable references . Unsourced material may be challenged and removed (September 2009) Probability theory is the branch of mathematics concerned with analysis of random phenomena. The central objects of probability theory are random variables stochastic processes , and events : mathematical abstractions of non-deterministic events or measured quantities that may either be single occurrences or evolve over time in an apparently random fashion. Although an individual coin toss or the roll of a die is a random event, if repeated many times the sequence of random events will exhibit certain statistical patterns, which can be studied and predicted. Two representative mathematical results describing such patterns are the law of large numbers and the central limit theorem As a mathematical foundation for statistics , probability theory is essential to many human activities that involve quantitative analysis of large sets of data. Methods of probability theory also apply to descriptions of complex systems given only partial knowledge of their state, as in statistical mechanics . A great discovery of twentieth century physics was the probabilistic nature of physical phenomena at atomic scales, described in

Algebra Applied Mathematics Calculus and Analysis Discrete Mathematics ... Interactive Demonstrations Probability Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions. In common usage, the word "probability" is used to mean the chance that a particular event (or set of events) will occur expressed on a linear scale from (impossibility) to 1 (certainty), also expressed as a percentage between and 100%. The analysis of events governed by probability is called statistics There are several competing interpretations of the actual "meaning" of probabilities. Frequentists view probability simply as a measure of the frequency of outcomes (the more conventional interpretation), while Bayesians treat probability more subjectively as a statistical procedure that endeavors to estimate parameters of an underlying distribution based on the observed distribution. A properly normalized function that assigns a probability "density" to each possible outcome within some interval is called a probability density function (or probability distribution function), and its cumulative value (integral for a continuous distribution or sum for a discrete distribution) is called a

The study of probability helps us figure out the likelihood of something happening. For instance, when you roll a pair of dice, you might ask how likely you are to roll a seven. In math, we call the "something happening" an "event." The probability of the occurrence of an event can be expressed as a fraction or a decimal from to 1. Events that are unlikely will have a probability near 0, and events that are likely to happen have probabilities near 1.* In any probability problem, it is very important to identify all the different outcomes that could occur. For instance, in the question about the dice, you must figure out all the different ways the dice could land, and all the different ways you could roll a seven. * Note that when you're dealing with an infinite number of possible events, an event that could conceivably happen might have probability zero. Consider the example of picking a random number between 1 and 10 - what is the probability that you'll pick 5.0724? It's zero, but it could happen.

Generally, however, most people do not have a definite idea about the meaning of statistical probability. The origin of the probability theory starts from the study of games like cards, tossing coins, dice, etc. But in modern times, probability has great importance in decision making. According to the classical theory, probability is the ratio of the favorable case to the total number of equally likely cases. Empirical or relative frequency probability is based on logic, past experience and present condition. According to the subjective approach, the probability of an event is assigned by an individual on the basis of evidences available to him/her.

Bayes' Rule The probability of an outcome of a particular event happening is the chance or likelihood of it happening. We all have an intuitive understanding of whether something is likely to happen, but mathematically we can determine how likely something is exactly. Events and outcomes An event is something that happens. It may not be very large or grand (e.g. tossing a coin is an event), and it may not happen at all (being knocked down by a bus is an event, but if I decide not to leave the house, it won�t happen). An event has outcomes . These are possible things that could arise from the event. For instance, buying a raffle ticket is an event. It has two basic outcomes: Either you win or you don�t! Mathematical values for probability Probabilities are constrained mathematically to lie between two limits: represents "impossibility" (something simply cannot happen) and 1 represents "certainty" (guaranteed to happen). These are two extremes, and most probabilities lie somewhere between them. You can think of the probability ranges as being a short number line running from at one end to 1 at the other:
