There are numbers from 1 to 100. A number is chosen at random, the probability that the sum of the digits of the chosen number 9 is
The concept of probability plays a vital role in mathematics, and CBSE 2024-2025 NCERT Maths Class 11th Chapter 14 Probability provides a strong foundation for it. This chapter covers random experiments, outcomes, sample space, events and probability of events. MCQ questions help students test their ability to apply probability rules, analyze different scenarios and calculate probabilities accurately. Practicing these questions enhances problem-solving skills, logical thinking and accuracy. A good understanding of probability is essential for higher studies in mathematics, statistics and science. Regular MCQ practice boosts confidence and prepares students for exams and real-world applications like finance and risk analysis.

Choice (c) is correct.
Since each number is equally likely to be chosen so, the sample space has 100 (equally likely) sample points.
Following are the 10 favourable sample points or outcomes:
9, 18, 27, 36, 45, 54, 63, 72, 81, 90
Thus, the required probability = 10/100 = 1/10
