If A and B are two events in a probability experiment, then the probability that either one of the events will occur is:. This can be represented in a Venn diagram as:. If you take out a single card from a regular pack of cards, what is probability that the card is either an ace or spade? Let X be the event of picking an ace and Y be the event of picking a spade. The two events are not mutually exclusive, as there is one favorable outcome in which the card can be both an ace and spade.

A probability gives the likelihood that a defined event will occur. It is quantified as a positive number between 0 the event is impossible and 1 the event is certain. Thus, the higher the probability of a given event, the more likely it is to occur. If A is a defined event, then the probability of A occurring is expressed as P A. Probability can be expressed in a number of ways. A frequentist approach is to observe a number of particular events out of a total number of events.

## PRACTICE PROBLEMS ON ADDITION THEOREM OF PROBABILITY

The probability of happening an event can easily be found using the definition of probability. But just the definition cannot be used to find the probability of happening at least one of the given events. The event of getting 2 heads, A and the event of getting 2 tails, B when two coins are tossed are mutually exclusive. Two events are said to be mutually exhaustive if there is a certainty of occurring at least one of those two events. If A and B are two mutually exhaustive then the probability of their union is 1. The event of getting a head and the event of getting a tail when a coin is tossed are mutually exhaustive. Addition theorem on probability:.

The addition rule states the probability of two events is the sum of the probability that either will happen minus the probability that both will happen. The addition rule is summarized by the formula:. Consider the following example. The addition law then simplifies to:. Suppose a card is drawn from a deck of 52 playing cards: what is the probability of getting a king or a queen? These two events are disjoint, since there are no kings that are also queens. This rule can be written:.

In the previous section, we introduced probability as a way to quantify the uncertainty that arises from conducting experiments using a random sample from the population of interest. We saw that the probability of an event for example, the event that a randomly chosen person has blood type O can be estimated by the relative frequency with which the event occurs in a long series of trials. So we would collect data from lots of individuals to estimate the probability of someone having blood type O. In this section, we will establish the basic methods and principles for finding probabilities of events. We will also cover some of the basic rules of probability which can be used to calculate probabilities. Since heads and tails are equally likely for each toss in this scenario, each of the possibilities which can result from three tosses will also be equally likely so that we can list all possible values and use this list to calculate probabilities.

If A and B are independent events associated with a random experiment, then P(A∩B) = P(A). P(B) i.e., the probability of simultaneous occurrence of two independent events is equal to the product of their probabilities.

## Addition Rules for Probability

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. A simple example is the tossing of a fair unbiased coin. These concepts have been given an axiomatic mathematical formalization in probability theory , which is used widely in areas of study such as statistics , mathematics , science , finance , gambling , artificial intelligence , machine learning , computer science , game theory , and philosophy to, for example, draw inferences about the expected frequency of events. Probability theory is also used to describe the underlying mechanics and regularities of complex systems.

- Я спущусь вниз, в подсобное помещение, и выключу рубильник. Стратмор медленно повернулся. Он являл собой печальное зрелище. - Это сделаю я, - сказал он, встал и, спотыкаясь, начал выбираться из-за стола. Сьюзан, чуть подтолкнув, усадила его на место.

Джабба всплеснул руками. - Ради всего святого. Шифры-убийцы похожи на любые другие - они так же произвольны. Угадать ключи к ним невозможно. Если вы думаете, что можно ввести шестьсот миллионов ключей за сорок пять минут, то пожалуйста.

Последний шанс. Но мы его упустили. - Не могу с ним не согласиться, - заметил Фонтейн. - Сомневаюсь, что Танкадо пошел бы на риск, дав нам возможность угадать ключ к шифру-убийце. Сьюзан рассеянно кивнула, но тут же вспомнила, как Танкадо отдал им Северную Дакоту. Она вглядывалась в группы из четырех знаков, допуская, что Танкадо играет с ними в кошки-мышки.

Ну, мы не сумели этого сделать. - А вдруг Танкадо умнее. - Может .

Такси было уже совсем рядом, и, бросив взгляд влево, Беккер увидел, что Халохот снова поднимает револьвер. Повинуясь инстинкту, он резко нажал на тормоза, но мотоцикл не остановился на скользком от машинного масла полу. Веспу понесло .

* Джабба, дело очень серьезное. У меня чутье. У нее чутье.*

The probability of event A or event B can be found by adding the probability of the separate events A and B and subtracting any intersection of the two events.
