Class 12 Mathematics — Probability Important Questions with Answers (Long answers)

Class 12 Mathematics board is relations-functions, inverse trig, matrices-determinants, calculus (continuity to differential equations), vectors-3D and probability (Bayes, distribution). This hub writes 150+ NCERT-true items. “Integrals class 12 important questions” and “matrices MCQ” are the chips. Twenty questions a page; the key stays closed. No leaked CBSE paper claims.

Probability — प्रायिकता

Conditional, Bayes, multiplication, and a Bernoulli/binomial distribution as the book keeps it. Independent ⇒ P(A∩B)=P(A)P(B). A random variable’s expectation is the last cluster. Write the partition events before Bayes. You are on Probability (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.

Q.169 Long Probability

Class 12 Mathematics — Probability पर एक unit-test उत्तर लिखें (परिचय, 4 बिंदु, निष्कर्ष)।

View the correct answer

Conditional, Bayes, multiplication, and a Bernoulli/binomial distribution as the book keeps it. Independent ⇒ P(A∩B)=P(A)P(B). A random variable’s expectation is the last cluster. Write the partition events before Bayes.

चार बिंदु: (1) NCERT परिभाषा/सूत्र/घटना। (2) एक उदाहरण या आरेख-विचार। (3) एक तुलना या कारण। (4) एक साधारण संख्यात्मक या उद्धरण यदि पाठ माँगता है।
निष्कर्ष: उत्तर अध्याय-सत्य रखें — बोर्ड की डेटशीट यहाँ नहीं गढ़ी गई।
