Delve into the intriguing world of chance and predictability with the CBSE Class 10 Mathematics chapter "Probability." This chapter opens the door to understanding how probability plays a vital role in various aspects of everyday life and scientific inquiry.
Introduction to CBSE Class 10 Mathematics Chapter "Probability"
“Probability” is a fascinating chapter that acquaints Class 10 students with the mathematical study of random events and the likelihood of occurrences. This chapter establishes the fundamental principle that probability is a measure ranging from 0 to 1, where 0 indicates impossibility and 1 indicates certainty. The chapter explores various approaches to determining the probability of events, including theoretical probability and its practical applications.
Students learn how to calculate the probability of simple events by considering the ratio of the number of favorable outcomes to the total number of possible outcomes. The chapter introduces the concept of sample space and different types of events, such as mutually exclusive and exhaustive events. It further delves into compound probability and the addition and multiplication rules of probability, enhancing students’ understanding of more complex probability scenarios.
The chapter is rich with examples and exercises that illustrate the use of probability in real life, such as in games of chance, weather forecasting, and risk assessment. Through the exercises, students learn to apply the formulas and concepts to solve problems efficiently and accurately.

Questions and Answers for CBSE Class 10 Mathematics Chapter "Probability"
- Q1: What is probability in mathematics? ANS: Probability is a branch of mathematics that deals with calculating the likelihood of a given event’s occurrence, which is expressed as a number between 0 and 1.
- Q2: How do you calculate the probability of an event? ANS: The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
- Q3: What is a sample space? ANS: A sample space is the set of all possible outcomes of a random experiment.
- Q4: What are mutually exclusive events? ANS: Mutually exclusive events are events that cannot occur at the same time. If one event occurs, the other cannot.
- Q5: How are the addition and multiplication rules used in probability? ANS: The addition rule is used to find the probability of the union of two events, while the multiplication rule is used to find the probability of the intersection of two independent events.
- Q6: What is a compound event in probability? ANS: A compound event is the result of two or more simple events, also known as a combination of simple events.
- Q7: Can probability help in predicting precise outcomes? ANS: Probability can predict the likelihood of outcomes, but it does not give precise predictions. It deals with the chances of occurrences.
- Q8: Why do we study probability? ANS: We study probability to understand and quantify the chance of events occurring, which is essential in fields such as finance, insurance, science, and daily life decision-making.
- Q9: What is theoretical probability? ANS: Theoretical probability is calculated based on the possible outcomes in a perfect world, without any actual experiments or trials.
- Q10: How is probability used in real life? ANS: Probability is used in various real-life applications, including risk assessment, insurance policies, weather forecasting, games of chance, and in making informed decisions under uncertainty.
