Chapter 15: Navodaya Class 9 Mathematics Probability

Have you ever wondered what may happen when you toss a coin or roll a dice? Can you tell if an event is certain or just possible? This is where Navodaya Class 9 Mathematics Probability becomes useful. Probability helps students understand the chance of an event.


In this chapter, students learn how to find the chance of different events. Moreover, they learn how to use simple formulas and solve questions step by step. Therefore, Navodaya Class 9 Mathematics Probability is an important topic for students preparing for the JNVST Class 9 entrance exam. With regular practice, students can understand JNVST Class 9 Maths Probability with ease. Also, these ideas can help students solve questions with better speed and confidence.


Therefore, for a better understanding, students can join the best online classes for Navodaya Vidyalaya  Class 9 at Veda Academy. We provide the best study material that is aligned with the updated JNV syllabus. JNVST Mock Tests, Model Papers, Notes, PYQs, and Important Questions.

What Is Probability?

Probability tells us how likely an event is to happen. In simple words, it tells us about the chance of an event. For example, when you toss a coin, it can show either heads or tails. Therefore, the chance of getting heads is equal to the chance of getting tails.


The basic formula used in Navodaya Class 9 Mathematics Probability is: Probability of an event = Number of favourable outcomes / Total number of possible outcomes. For example, a dice has six faces. If you want to find the chance of getting a 4, there is one favourable outcome and six possible outcomes. So: Probability of getting 4 = 1/6. This simple idea forms the base of JNVST Class 9 Maths Probability.

Important Terms in Probability

Students should know a few basic terms before solving Navodaya Class 9 Mathematics Probability questions.


  1. Experiment: An experiment is an activity that gives an outcome. For example, tossing a coin is an experiment.

  2. Outcome: An outcome is the result of an experiment. For example, getting heads after tossing a coin is an outcome.

  3. Sample Space: The sample space contains all possible outcomes. For one coin toss: S = {Heads, Tails}

  4. Event: An event is a particular result or group of results that we want to study. For example, getting an even number when rolling a dice is an event. These terms are also useful in JNVST Mathematics Class 9 preparation.

Probability of an Event

The probability of an event always lies between 0 and 1.


  • Probability 0 means the event is impossible.

  • Probability 1 means the event is certain.

  • A value between 0 and 1 shows that the event may happen.


For example, getting 7 on a normal six-sided dice is impossible. Therefore, its probability is 0.

On the other hand, getting a number from 1 to 6 on the same dice is certain. Therefore, its probability is 1. Understanding these simple points makes Navodaya Class 9 Mathematics Probability easier.

Probability Questions for JNVST Class 9

Students preparing for JNVST Class 9 Maths Probability should practise different types of questions. For example, questions may use coins, dice, cards, balls, or simple daily-life situations.


While solving a question, first read it carefully. Next, find the total outcomes. Then, find the favourable outcomes. Finally, use the probability formula. This method makes Navodaya Class 9 Mathematics Probability questions easier to understand.

Tips to Prepare for Probability

Good preparation needs regular practice. Therefore, students should follow a simple study plan.


  1. First, understand the meaning of probability.

  2. Next, learn the important terms.

  3. Then, remember the basic formula.

  4. After that, solve easy questions.

  5. Gradually, try mixed questions.

  6. Finally, revise mistakes and important formulas.


Students can also use Navodaya Class 9 Maths Notes for quick revision. In addition, practice tests can help students check their understanding. The JNV Syllabus should always guide exam preparation. Students should study each topic carefully instead of focusing only on one type of question.
