The Concept of Probability

Probability is the theory of quantifying the chance of an event occurring (or not occurring). While the theory is vast in itself, for the purpose of exam, very elementary questions are asked and hence we will stick to just the basics. All the questions of probability that are asked in entrance exams are based on discrete events and in the case of discrete events, probability is defined as:

Probability of an event occurring =(Number of favourable outcomes) / (Total number of possible outcomes)

By the formula it should be evident that probability can never be more than 1 because the number of favourable outcomes can never be more than the total number of outcomes.

Our Research & Findings

#IBPS PO

As a sample we have choosen the last 4 year's (2019, 2018, 2017, 2016) previously asked question papers. In quatitative aptitude section, a total number of questions asked are 35. Out of these 35 questions 2.86% of questions are from Probability.

#SBIPO
