**CBSE Chapter 13 Class 12 Maths- Probability: 13.1: Introduction**

This section will teach you about the concepts about conditional probability, which will eventually help you work on Bayes’ theorem, independence of events along multiplication rule in probability. Well, there is more to study from this chapter, for now; let’s proceed with the next section which is a conditional probability.

**CBSE Chapter 13 Class 12 Maths- Probability: 13.2: Conditional Probability**

This section is simple and teaches you about how one single event might be responsible for changing the events of another corresponding event. The chapter covers all the minute details depicting the situation with quality examples which will be sufficient to get a thorough idea to work with the sums.

**CBSE Chapter 13 Class 12 Maths- Probability: 13.3: Multiplication Theorem on probability**

Once you learned and understood the conditional probability, getting to know and study this notion becomes a lot easier.** Probability NCERT Solutions Class 12** is a substantial study resource. Therefore with this course content students are bound to grasp the topic in no time. Additionally, since the chapter is practical in tone, make sure to maintain a regular practice session.

**CBSE Probability NCERT Solutions Class 12: 13.4: Independent Events**

This section talks about those events which occur without affecting any other of that sort. Take, for instance, you flip a coin, you already assume that there is a general outcome of the event. Either it’s a tail or a head, isn’t it? And in each situation, none of the events affects the other.

With a thorough study session on the NCERT Solutions for Class 12 Maths Chapter 13 and several practice sessions we assure you, you will get every corner of the section competently.

**CBSE ****Probability NCERT Solutions Class 12: ****13.5: Bayes’ theorem**

This section introduces you to Bayes’ theorem which teaches about the probability of an event occurring which is relevant to any conditions. Well, this situation often resembles conditional probability.

Take, for instance, you own a bag that has three balls of three different colors, which are blue, yellow, and red. You will have to estimate the probability of taking out the number of yellow balls from the three colors. In this situation, the event occurring is measured depending on the other probable conditions which is the conditional probability.

**CBSE ****Probability NCERT Solutions Class 12: ****13.6 Random Variables and its Probability distribution**

The probability of distribution of a random value is what determines the probability of its value which is unknown. A random variable can either be continuous or discrete or both. The chapter is loaded with many interesting notions for you to discover once you grab your NCERT Solutions for Class 12 Maths Chapter 13 from here.

**CBSE ****Probability NCERT Solutions Class 12: ****13.7: Bernoulli Trial and Binomial Distribution**

Here in this portion of the chapter, you will get a close look at the Bernoulli trial and Binomial distribution but in brief. Bernoulli trial or binomial trial comes out with only two possible results. Get yourself CBSE class 12 maths – chapter 13 pdf to jet start your exams preparation right here, right now.

**CBSE Class 12 Maths- Chapter 13: Important theories and formulas**

- 0 ≤ P (E|F) ≤ 1, P (E′|F) = 1 – P (E|F)P ((E ∪ F)|G) = P (E|G) + P (F|G) – P ((E ∩ F)|G)
- P (E ∩ F) = P (E) P (F|E), P (E) ≠ 0P (E ∩ F) = P (F) P (E|F), P (F) ≠ 0
- If E and F are independent, thenP (E ∩ F) = P (E) P (F)P (E|F) = P (E), P (F) ≠ 0P (F|E) = P (F), P(E) ≠ 0
- Theorem of total probability
- Bayes’ theorem
- A random variable is a real-valued function whose domain is the sample space of a random experiment.
- Var (X) = E (X2) – [E(X)]2
- Trials of a random experiment are called Bernoulli trials if they satisfy the
- following conditions :
- There should be a finite number of trials.
- The trials should be independent.
- Each trial has exactly two outcomes: success or failure.
- The probability of success remains the same in each trial.
