Grasp Concepts with RD Sharma Class 12 Maths Solutions Chapter 31 - Probability

Q: 1. What is the law of total probability?

Let {E1, E2, ..., En } be a partition of a sample space S, such that each of E1, E2, ..., En has a nonzero probability. Let A be an event associated with S, then according to the law of total probability P(A) = P(E1) P (A|E1 ) + P (E2) P (A|E2 ) + ... + P (En) P(A|En )

Class 12 RD Sharma Textbook Solutions Chapter 31 - Probability

Probability RD Sharma Class 12 we will be more concerned about the axiomatic approach of probability towards solving a problem. In this chapter, we have established the equivalence between the axiomatic theory of probability and the Classical theory of probability in the case of equally likely outcomes. On the basis of this relationship, we have obtained probabilities of events associated with discrete sample spaces.

In continuation of the addition theorem of probability, we will also introduce the concept of conditional probability which will be useful in obtaining. We can use this concept to derive a formula for conditional probability. We will be discussing theorems that are helpful in computing the probabilities of simultaneous occurrences of two or more events associated with a random experiment which is also known as the multiplication theorem of probability. Our Subject matter experts have prepared and even designed solutions so that students will be having a lot of fun while solving it.

FAQs on Grasp Concepts with RD Sharma Class 12 Maths Solutions Chapter 31 - Probability

1. What is the law of total probability?

Let {E₁, E₂, ..., E_n } be a partition of a sample space S, such that each of E₁, E₂, ..., En has a nonzero probability. Let A be an event associated with S, then according to the law of total probability P(A) = P(E₁) P (A|E₁ ) + P (E₂) P (A|E₂ ) + ... + P (E_n) P(A|E_n )

2. What is a random variable?

A random variable can be defined as a real-valued function for which domain is the sample space of a random experiment.

3. What is meant by conditional probability?

Conditional probability is the chance of occurrence of an event, based on the occurrence of a previous event or outcome. The conditional probability of an event B, given the occurrence of the event A can be calculated using the formula P(B|A) = P(A∩B) / P(A)
