How to Calculate Probability? Probability is the mathematical calculation used to calculate the occurrence of all the possibilities for an event to occur in certain random circumstances. Usually, the probability is calculated based on the value between 0 and 1. If the answer is closer to the unit value, the level of certainty is determined. But if the answer is closer to Zero, then the level of certainty is less. Certain questions often arise in this topic like, How is a probability calculated for an event? The probability is a chance of prediction of an event. For example, let us assume the chances of an event happening be x, then the chances of an event not happening be 1-x. So, to calculate the probability, the probability formula is used. In this article, we explained how is probability calculated? probability formula for bank exam, probability formulas with examples, probability formula example, probability examples and solutions, simple probability examples and solutions, probability formula for aptitude, probability problems with solutions and answers pdf, basic probability problems with solutions, probability formula for aptitude, probability problems with solutions pdf download, probability pdf notes, probability formula example problems, probability equation example, probability formula pdf download, probability formula pdf, probability definition, formula for conditional probability, conditional probability definition, and so on in detail.

Probability Definition

In this Probability Formula for Bank Exam article you can learn about the probability definition and how is probability calculated in the quantitative aptitude section of the bank exams, conditional probability definition, conditional probability formula, and different Probability Formulas with Examples. Probability defines the likelihood of occurrence of an event. There are many real-life situations in which we may have to predict the outcome of an event. We may be sure or not sure about some of the programs or events. In that situation, we can say that there is a probability for the event to occur. This is called the probability definition and the same procedure will apply to the probability problems on the quantitative aptitude section of the bank exams. Candidates can download the probability formula pdf which is attached to this Probability Formula For Bank Exam article to know the probability definition.

Probability Formulas For Bank Exam

The Probability Formula For Bank Exam is given below. Aspirants can go through this Probability Formula For Bank Exam article to be proficient with the probability formulas. You can also download the probability formula pdf for your future reference. By exploiting this probability formula you will get to know how is probability calculated for the bank and other competitive exams.

         

(or) P(A) = n(A)/n(S)

Where,

• P(A) is the probability of an event “A”

• n(A) is the number of favourable outcomes

• n(S) is the total number of events in the sample space

 

In this Probability Formulas For Bank Exam post, we have provided some basic probability formulas for the banking aspirants. Candidates can check these basic probability formulas in this Probability Formula For Bank Exam article or you can download the probability formula pdf. They are, 

• Probability Range

• Rule of Addition

• Rule of Complementary Events

• Disjoint Events

• Independent Events

• Conditional Probability

• Bayes Formula

 

The aspirants can check the table which is given below to learn more probability formulas for bank exams here. Let A and B be two events. The probability formulas are listed below:

 

Basic Probability Formulas
Probability Range	0 ≤ P(A) ≤ 1
Rule of Addition	P(A∪B) = P(A) + P(B) – P(A∩B)
Rule of Complementary Events	P(A’) + P(A) = 1
Disjoint Events	P(A∩B) = 0
Independent Events	P(A∩B) = P(A) ⋅ P(B))
Conditional Probability	P(A | B) = P(A∩B) / P(B)
Bayes Formula	P(A | B) = P(B | A) ⋅ P(A) / P(B)

 

Conditional Probability Definition

We have provided the conditional probability definition and formula for conditional probability in this Probability Formulas For Bank Exam post. You will come to know how is probability calculated, conditional probability definition and formula for conditional probability by utilizing this math Probability Formula For Bank Exam article. Conditional probability is known as the possibility of an event or outcome happening, based on the existence of a previous event or outcome. It is calculated by multiplying the probability of the preceding event by the renewed probability of the succeeding, or conditional, event. This is the proper conditional probability definition. You shall check the formula for conditional probability. The formula for conditional probability is,

Formula for Conditional Probability = P(A | B) = P(A∩B) / P(B)

Probability Formulas with Examples

We have come up with the Probability Formulas with Examples in this probability formula pdf for bank exams article. Candidates can exploit these Probability Formulas with Examples to know how is probability calculated by using the probability formula. You can download the probability formula pdf and start your preparation effectively.

Example 1: What is the probability that a card taken from a standard deck, is a King?

Solution:

Total number of cards a standard deck contains = 52

Number of King cards in a deck of cards = 4

So, the number of favourable outcomes = 4

Now, by using the formula,

Probability of selecting a king from a deck is,

P(King) = (Number of favourable outcomes) / (Total number of favourable outcomes)

P(King) = 4/52

= 1/13

So here we have the probability of getting a king in a standard deck is 1/13.

Example 2: In a bag, there are 6 black balls and 8 blue balls. One ball is selected randomly from the bag. Find the probability of getting a black ball.

Solution:

Let us assume the probability of drawing a black ball to be P(B)

Number of favourable outcomes to get a black ball = 6

Total number of balls in the bag = black balls + blue balls = 14

P(B) = Number of favourable outcomes/Total number of outcomes = 6/14 = 3/7

So, the probability of drawing a black ball in a bag is 3/7.
