Events in probability can be defined as certain likely outcomes of an experiment that form a subset of a finite sample space. The probability of occurrence of any event will always lie between 0 and 1. There could be many events associated with one sample space.
Suppose a fair die is rolled. The total number of possible outcomes will form the sample space and are given by {1, 2, 3, 4, 5, 6}. Let an event, E, be defined as getting an even number on the die. Then E = {2, 4, 6}. Thus, it can be seen that E is a subset of the sample space and is an outcome of the rolling of a die. There are several different t...
Independent eventsin probability are those events whose outcome does not depend on some previous outcome. No matter how many times an experiment has been conducted the probability of occurrence of independent events will be the same. For example, tossing a coin is an independent event in probability. Dependent eventsin probability are events whose ...
An event that can never happen is known as an impossible event. As impossible events in probability will never take place thus, the chance that they will occur is always 0. For example, the sun revolving around the earth is an impossible event. A sure event is one that will always happen. The probability of occurrence of a sure event will always be...
If an event consists of a single point or a single result from the sample space, it is termed a simple event. The event of getting less than 2 on rolling a fair die, denoted as E = {1}, is an example of a simple event. If an event consists of more than a single result from the sample space, it is called a compound event. An example of a compound ev...
When there are two events such that one event can occur if and only if the other does not take place then such events are known as complementary events in probability. The sum of the probability of complementary events will always be equal to 1. For example, on tossing a coin let E be defined as getting a head. Then the complement of E is E' which ...
Events that cannot occur at the same time are known as mutually exclusive events. Thus, mutually exclusive events in probability do not have any common outcomes. For example, S = {10, 9, 8, 7, 6, 5, 4}, A = {4, 6, 7} and B = {10, 9, 8}. As there is nothing common between sets A and B thus, they are mutually exclusive events.
Exhaustive eventsin probability are those events when taken together from the sample space of a random experiment. In other words, a set of events out of which at least one is sure to occur when the experiment is performed are exhaustive events. For example, the outcome of an exam is either passing or failing.
Equally likely events in probability are those events in which the outcomes are equally possible. For example, on tossing a coin, getting a head or getting a tail, are equally likely events. The intersection of events in probability corresponds to the AND event. If two events are associated with the "AND" operator, it implies that the common outcom...
May 21, 2024 · In this article, we’ll explore the various types of events in probability, including simple events, compound events, mutually exclusive events, independent events, and dependent events. So, let’s dive into the world of different types of events.
The probability (with respect to some probability measure) that an event occurs is the probability that contains the outcome of an experiment (that is, it is the probability that ). An event defines a complementary event , namely the complementary set (the event not occurring), and together these define a Bernoulli trial : did the event occur ...
Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event.
The probability of any event is defined as the chance of occurrence of the events to the total possible outcomes. If there are ‘n’ exhaustive, mutually exclusive and equally likely outcomes of a random experiment. Out of which, ‘m’ are favorable to the occurrence of an event E.
Probability: Types of Events. Life is full of random events! You need to get a "feel" for them to be smart and successful. The toss of a coin, throw of a dice and lottery draws are all examples of random events. Events. An "Event" can be one or more outcomes. Examples: An event can be one outcome: Getting a Tail when tossing a coin is an event.
