Instructions
- 27 questions, single correct option each.
- Marking (JEE Main pattern): for a correct answer, for a wrong answer, for unattempted. Maximum: 108.
- Time limit: 60 minutes. Set a timer before you begin and attempt the paper in one sitting.
- Work on rough paper; no calculator. Decide fast whether to count directly or through the complement — that one decision is most of the time cost per question.
| Score band | Verdict |
|---|---|
| 85 - 108 | Excellent — probability is a scoring topic for you |
| 60 - 84 | Solid — review the questions you missed, mostly counting slips |
| 35 - 59 | Revise the addition rule, complements, and Chapter 6 counting |
| below 35 | Rework Sections 1-3 and the Solved Examples before retrying |
After this chapter: Class 11 ends here — and Class 12 probability picks up exactly where this stops: conditional probability, independence, Bayes' theorem and probability distributions all build directly on the axioms and the addition rule you just mastered.
Disclaimer: These questions are modelled on the JEE Main pattern and difficulty; they are practice questions in the exam style, not reproductions of specific past papers.
