NCERT Solutions for Class 12 Maths Chapter 13, focusing on the intriguing realm of probability. In this blog, we'll delve into the intricacies of Exercise 13.2, providing step-by-step solutions to help you ace this crucial chapter.

Understanding Probability


We discussed the axiomatic approach formulated by Russian Mathematician A.N. Kolmogorov (1903-1987) and treated probability as a function of the outcomes of the experiment. Probability is a fascinating branch of mathematics that deals with the likelihood of events occurring in various situations. Whether it's predicting the outcome of a dice roll, the probability of drawing a particular card from a deck, or the chances of rain on a given day, probability concepts are all around us.

Exercise 13.2 of Class 12 Maths Chapter 13 focuses on Conditional Probability. The concept of conditional probability is where the probability of an event is determined by certain conditions or constraints.


Here's a brief overview of the topics covered in Exercise 13.2

  1. Conditional Probability: Understand the concept of conditional probability, where the likelihood of an event A occurring is dependent on the occurrence of another event B.
  2. Conditional Probability Formula: Learn how to calculate conditional probability using the formula P(A|B) = P(A ∩ B) / P(B), where P(A|B) represents the probability of event A given that event B has occurred.
  3. Solving Problems: Practice solving a variety of problems involving conditional probability, including real-life scenarios and theoretical examples.
