Understanding Case Study Questions on Probability Class 10

Math Case Study Questions on Probability Class 10 deal with applying probability concepts in practical scenarios. These include problems related to dice, playing cards, coins, and even daily life events. Moreover, by practicing Class 10 Probability Case Study Questions, students not only strengthen their analytical but also their logical reasoning. In addition, these questions provide an exam-oriented approach, which is essential for success in case study questions . Consequently, students are better equipped to handle challenging board-level problems with confidence.

Importance of Case Study Based Probability Questions

Working on Case Study Questions helps students develop a deeper understanding of random events. Additionally, Ncert Case Study Questions Class 10 include solved examples that explain step-by-step solutions clearly. Furthermore, these examples guide learners in applying probability formulas correctly, and as a result, reduce common calculation mistakes. In fact, solving them regularly prepares students not only for school tests but also for crucial board exams. Hence, the importance of regular practice cannot be overstated.

Practice with Solved and Sample Questions

Students should also try Probability Case Study Questions With Solutions Class 10 for detailed explanations. Moreover, practicing Solved Case Study Questions Probability Class 10 ensures accuracy and steadily boosts exam confidence. Therefore, consistent revision using a balanced mix of NCERT and CBSE case study questions is highly recommended. Consequently, students develop both conceptual clarity and exam readiness, which ultimately results in better overall performance.

Case Study 3: Fun and Learn Fair Probability Activities

Case Study 3 Probability Class 10

The neighbourhood school organises an annual “Fun and Learn” fair where the Mathematics Department runs a raffle and a few chance-based stalls to teach students about probability through real-life examples. For the raffle, 100 numbered tickets (1 to 100) are sold and exactly 8 tickets are printed as winners; one ticket will be drawn at random to pick a lucky winner. At the “Sweet Pick” stall a volunteer blind-picks one sweet from a sealed box containing 20 sweets: 6 chocolates, 8 toffees and 6 biscuits. The mathematics teacher also prepares a small number-draw activity with tickets numbered 1 to 100 to discuss divisibility — students are asked to estimate the chance of picking a number divisible by 7. At the craft corner there is a transparent bag with 20 beads: 5 blue, 7 red and 8 yellow; a child picks one bead without looking. Finally, for a quick classroom exercise the teacher asks a student to pick a single ticket from numbers 1 to 50 (inclusive) to discuss primes and asks the probability that the chosen number is prime. All selections are single random draws with all outcomes assumed equally likely; students are required to use the classical definition of probability and reduce fractions to simplest form.

1. A ticket is drawn at random from the 100 raffle tickets among which 8 are winners. What is the probability that the drawn ticket is a winning ticket?

Answer: (b) 2/25

Solution: Total outcomes = 100. Favourable outcomes = 8. Probability = 8/100 = 2/25.

2. One sweet is chosen at random from the sealed box of 20 sweets (6 chocolates, 8 toffees, 6 biscuits). What is the probability that the chosen sweet is a chocolate?

Answer: (d) Both (a) and (c) are equivalent and correct

Solution: Total outcomes = 20. Favourable = 6. Probability = 6/20 = 3/10. Options (a) and (c) represent the same value; hence (d) is correct.

3. A ticket numbered from 1 to 100 is chosen at random. What is the probability that the number on the ticket is divisible by 7?

Answer: (d) 7/50

Solution: Numbers divisible by 7 up to 100 are 7,14,…,98. Count = 14. Probability = 14/100 = 7/50. Option (a) is the unsimplified fraction; (d) is the simplified equivalent.

4. A bead is picked at random from a bag containing 5 blue, 7 red and 8 yellow beads (total 20). What is the probability that the bead is not red?

Answer: (a) 13/20

Solution: Total = 20. Number of red beads = 7. Not red = 20 – 7 = 13. Probability = 13/20.

5. A single ticket is chosen at random from integers 1 to 50 inclusive. What is the probability that the chosen number is a prime number?

Answer: (d) Both (a) and (b) are equivalent and correct

Solution: Primes ≤ 50 are 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47; count = 15. Total outcomes = 50. Probability = 15/50 = 3/10. Options (a) and (b) are numerically the same; therefore (d) is correct.
