NCERT Class 10 Math Chapter 14 प्रायिकता (Probability) introduces students to the concept of chance and likelihood of events. In this chapter, students learn how to calculate the probability of simple events using the formula P(E) = Number of favourable outcomes ÷ Total number of outcomes. The chapter deals with real-life examples like tossing a coin, rolling a dice, or drawing cards, which makes the subject more interesting and practical. Since probability questions are common in board exams and are generally considered easy, this chapter is highly important for scoring well.

I am writing about this topic because probability is not only an important part of the Class 10 syllabus but also a concept that students will use in higher studies and real life. From predicting weather conditions to calculating risks in business, probability plays a key role. Many students initially find it confusing, but NCERT presents it in a simple and easy-to-understand manner. By practising from the NCERT book, students can build a strong foundation and develop confidence in solving probability problems. Having the PDF makes it easier for learners to access the chapter anytime, revise formulas, and attempt practice questions before exams.

Key Concepts in Chapter 14 प्रायिकता

This chapter focuses on:

• The definition of probability
• Probability of simple events
• Formula: P(E) = Number of favourable outcomes ÷ Total number of outcomes
• Practical examples using coins, dice, and cards
• Application-based word problems

Example Problem

If a dice is thrown once, what is the probability of getting an even number?

• Total outcomes = 6 (1, 2, 3, 4, 5, 6)
• Favourable outcomes = 3 (2, 4, 6)
• Probability = 3/6 = 1/2

Such examples make the concept clear and help students apply the formula correctly.
