  • 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.
  • Before going to solve probability questions by using probability tricks for bank exams you should know some important topics and explanations regarding probability topics. 

Experiment: Any procedure or event that we carry out. It must have a possible set of outcomes.

Sample Space(S):  It is a well-defined set of possible outcomes.

For example, 1) Sample space in tossing a coin on air = S = ( H, T)

                       2) If two coins are tossed then S = ( HH, HT, TH, TT )

Outcome: The result of the experiment.

Favorable Outcomes: The outcomes that are favorable to us.

Probability Range: Between 0 and 1

  • The important probability shortcut for bank exams is that the candidate should be familiar with some probability rules.  Some of the probability rules are provided in this probability tricks for Bank Exams article. They are, 

Addition rule: 

P (A or B) = P(A) + P(B

and P(A ∪ B) = P(A) + P(B)

Multiplication rule:

if A and B are independent events

P (A and B) = P(A) x P(B)

P(A ∩ B) = P(A) x P(B)

  • Probability Based on Coins: In probability based on coins type, questions are asked based on tossing coins and obtaining a particular face (Head/Tail) or obtaining the same face on two or more coins.
  • Probability Based on Dice: Probability Based on Dice type of question is based on rolling one or more dice and getting a particular number on the face or a sum of faces of dice.
