Equally Likely Events are the most common type of events that you will encounter in the IBPS PO, SO, SBI PO, Clerk and other similar exams. These are those events which are random and have thus an equal likelihood of occurrence.
Equally likely means that each outcome of an experiment occurs with equal probability. For example, if you toss a fair , six-sided die, each face (1, 2, 3, 4, 5, or 6) is as likely to occur as any other face.
When we say that events are “equally likely,” it means that each event has the same probability of occurring. In other words, the chances of each event happening are equal. For example, let’s say we have a fair, six-sided die.
When the events have the same theoretical probability of happening, then they are called equally likely events. The results of a sample space are called equally likely if all of them have the same probability of occurring.
In probability theory, an equally likely event refers to a set of outcomes or events in which each outcome has the same probability of occurring. In other words, when all the outcomes of an event are equally likely to happen, they have an equal chance of being the final outcome.
The probability of an event can only be between 0 and 1 and can also be written as a percentage. The probability of event A is often written as P (A) . If P (A) > P (B) , then event A has a higher chance of occurring than event B . If P (A) = P (B) , then events A and B are equally likely to occur.
Feb 3, 2021 · From this result, we see that in the context of equally likely outcomes calculating probabilities of events reduces to simply counting the number of outcomes in the event and the sample space. So, we take a break from our discussion of probability, and briefly introduce some counting techniques.
3.6 Equally likely outcomes In this section we’ll look more closely at how to compute probabilities when the outcomes in the sample space are equally likely. But a warning before proceeding: in most situations sample space outcomes are not equally likely!
Jul 18, 2022 · An experiment has equally likely outcomes if every outcome has the same probability of occurring. For equally likely outcomes, the probability of outcome A , P(A) , is: \[P(A)=\dfrac{ \text {number of ways for A to occur}}{\text { total number of outcomes }}. \nonumber \]
May 28, 2023 · How to: Given a probability event where each event is equally likely, construct a probability model. Identify every outcome. Determine the total number of possible outcomes.
