# PROBABILITY

**NCERT SOLUTIONS FOR CLASS 12 MATHS CHAPTER 13 PROBABILITY** is all about usage of probability in real life as well as need and importance of it.It is basically an important chapter where you will know how to calculate and estimate values. It is related to the surface calculation of every thing which is calculated in bulk amount.For example if you want to know the probability of getting face cards in the total bundle of cards then concept of probability is going to help you in such cases.

**Let’s know about Pierre De Fermat,**

Basically **Pierre De Ferma**t was a French Lawyer at the parliament of Toulouse,France. He was a mathematician too so that he is on our textbook in front of us.His contribution in mathematics led to early development of Infinitesimal Calculus along with the technique of Ad equality.He is mostly known for finding the greatest and smallest ordinates of the curved lines.Many notable contribution can be found in mathematics field including contribution to analytics geometry,**Probability** and optics.Among his popular principle Fermat’s Principle of Light Propagation and Fermat Last Theorem in Number Theory are the notable ones.Lets go through our main subjective topic.

## SOME IMPORTANT TERMINOLOGIES OF **NCERT SOLUTIONS FOR CLASS 12 MATHS CHAPTER 13 PROBABILITY.**

**Properties of conditional probability****Multiplication Theorem on Probability****Partition of a sample space****Probability distribution of a random variable****Mean of a random variable****Variance of a random variable****Bernoulli trials****Binomial distribution**

Briefing all the Terminologies from above,You will be learning many ways of calculating a probability of any thing from this chapter.To get 100% of good marks from this chapter you need to have ideas of those terminologies.So, here you will be learning the different properties of conditional probability.If the two different events occurs in the same time then Multiplication theorem on Probability will help you to find the probabilities.

You will get ideas about independent events too.So from the third point of terminologies above,The events P1, P2, …, Pn represent a partition of the sample space S if these are pairwise disjoint, exhaustive and have a nonzero probability.You will get covered by the concepts of probability’s distribution of a random variable,Mean of random variable,Variance of Random Variable,Bernoulli Trails and Binomial Distribution.

### #CLEARING OUT THE PROBABILITY.

After knowing about the probability briefly we provided you the **NCERT Solutions**. We strongly suggest and encourage the students to go through all the solutions from the **PDF File**.As they are the most probable questions along with answers. It has reduces time of the students.Understandable PDF File will help them to secure better marks in the** NCERT Board Examination**.

### #MOTIVATION FOR THE STUDENTS.

We the team of STUDYHUNT kindly request all the students to schedule the time table for the study. It means it will allow you to remain in discipline as well as you can play and enjoy the rest of your time except the scheduled one. By this you will get limited and there will be no chance of wastage of time.This interns, You all will score better marks in your Examinations.
