L 11 | Conditional Probability Problems | NCERT Level | Probability | JEE Mains & Advanced 2027

In this lecture, we study Conditional Probability in detail for JEE Mains and JEE Advanced. This is Lecture 11 of the Probability chapter, where we develop the concept rigorously and solve multiple exam-oriented problems involving area approach, finite sample spaces, non-equally likely events, and real-life interpretations. We start from the definition of conditional probability, understand how the sample space shrinks after information is given, and apply it to a wide variety of problems asked in JEE Mains, JEE Advanced, and other competitive exams. 🔍 What you will learn in this lecture: Definition of Conditional Probability Meaning of information gain Conditional probability using area models Problems based on finite & non-equally likely outcomes Family & card problems Coin–die mixed experiments Probability with percentages and real data Multiple conditional probability calculations on a single experiment This lecture is concept-focused, calculation-accurate, and Advanced-oriented, making it ideal for serious JEE aspirants. 📌 Recommended for: JEE 2026 | JEE 2027 | JEE 2028 | Droppers | Advanced Aspirants ⏱️ Detailed Timestamps 00:00 – Definition of Conditional Probability P(A|B) 01:56 – Area Based Conditional Probability Problem 09:94 – Evaluating P(A|B) Using Given Probabilities 11:25 – Family Problem: At Least One Child is a Boy 15:52 – Card Problem: Conditional Probability on Numbers 18:19 – Real Data Problem (School & Class XII Example) 23:23 – Coin Toss + Die Throw (Not-Equally Likely Outcomes) 31:50 – Conditional Probability with Percentages 33:43 – Multiple Events on a Single Die 41:13 – Important Observations & Exam Tips conditional probability conditional probability jee probability jee mains probability jee advanced conditional probability class 12 jee maths probability probability full lecture conditional probability problems jee advanced probability questions conditional probability explained probability chapter jee conditional probability examples jee maths full course probability for jee 2026 probability concepts jee #ConditionalProbability #JEEProbability #JEEMaths #JEEAdvanced #JEEMains #Probability #Class12Maths #JEE2026 #JEE2027 #MathsForJEE #AdvancedMaths #IntegronJEE
