Probability Tips & Practice Questions for SBI PO Prelims

Probability:

Questions based on probability can be asked in the following ways
i) To find the probability of an event

ii) To find the probability of a combination of different events

iii) To find the difference in the probability of occurrence of two or more different events.

Basics:

Probability is the measure that tells us how likely is an event to happen.

Let ‘P’ be the value of probability of occurrence of an event.

Then, 0 ≤ P ≤ 1

If an event is a certain event, i.e. if it is sure that the event is going to occur, then probability of the given event is ‘1’.

If an event is an impossible event i.e. if it is sure that the event cannot occur, then probability of occurrence of the given event is ‘0’.

Probability of two related events:

Consider the event of writing an examination. The given event has only two possible outcomes: passing the examination and failing the examination.

Let ‘P’ be the probability of passing the examination and let ‘Q’ be the probability of failing the examination. Then (P + Q) = 1.

Following the same principle, if ‘P’ be the probability of a person passing the exam, then the probability of the person failing the exam is (1 – P).

Classical definition of probability = Number of favorable events in the outcome ÷ total number of events in the outcome

The set of all possible events is called the sample space.

The set of events which is of interest to us is called the event.

Then, probability of a given event = n(E) ÷ n(S)

Bias – When the probability of a certain event is different than the usually expected probability, then the occurrence of the event is said to be biased. For example, while tossing a coin, if the probability of getting a head and a tail are not the equal, then the coin is said to be a biased coin.

Let ‘E₁’ and ‘E₂’ be two different events where the probability of occurrence of ‘E₁’ and ‘E₂’ is ‘p’ and ‘q’, respectively

Then, the probability of occurrence of both ‘E₁’ and ‘E₂’ = (p × q).

Strategies for SBI PO Probability Questions Problem Solving

Understanding the Problem Read carefully to identify the type of event Organizing Information Use of diagrams, tables, and lists Use Formulas Wisely Familiarise yourself with important probability formulas and concepts Practice Time Management Solve easier first, then move on to more complex questions Elimination of Options Elimination techniques in case of MCQs Preparation Strategy for SBI PO Probability Questions

Master Basics: Acquire a clear understanding of basic probability concepts.

Refer to Previous Year Papers: Understand the trend and trend of past questions in the SBI PO exam. We are providing you the link to the previous year question paper so that you can understand the trend of the previous year and keep your preparation based on them.

Take Mock Tests: Practice helps in speed and accuracy for the candidate with mock tests. Candidates should take mock tests and understand their weak areas so that they can focus on them as much as possible.

Work on Weak Areas: Spot the weak areas in probability concepts and practice specifically on those issues.

Revision is the key to remembering: Practice the formulas regularly and recall all the concepts, So that you remember that topic for a long time.
