For example, you have collected data on marks in maths obtained in the class. From this data, you will understand how many students have passed, how many students got a full mark, what is the most repeated mark, what is the average of the mark, etc. You will study how to arrange data and how to obtain certain results from them in this chapter.

NCERT Solutions for Class 9 Maths Chapter 15

Probability Class 9 Solutions: Probability means chances of happening something. It is one of the best chapters you will learn in 9th 9 maths. We used to say there was a chance for rain today, there is a chance for India to win the match, etc. All our predictions are based on certain previous observations. Consider that you are throwing a die. Then you may get 1, 2, 3, 4, 5 or 6. That is, there are six outcomes in the experiment of throwing a die. We will say the probability or chance of getting a 3 on die is 1/6. In this chapter, you are going to study how these probabilities are calculated.
