Probability Mastery: The Ultimate Guide (Part 4)

Struggling with complex probability problems? You’re not alone. In Part 4 of our Probability Series, we’re breaking down the advanced concepts that usually confuse students in exams and real-world data science. Whether you're preparing for college finals, competitive exams like the SAT/GRE, or just want to understand the math behind AI and risk assessment, this video is for you! In this video, we cover: ✅ The "Secret" to solving [Sub-topic] problems in seconds. ✅ Why [Concept] is essential for Machine Learning and AI in 2026. ✅ Step-by-step walkthroughs of the trickiest exam questions. ✅ Common mistakes that 90% of students make (and how to avoid them). The video covers: Calculating the probability of a defective bulb (0:08-1:17): The instructor explains how to calculate the probability of drawing a defective bulb from a batch where 4 out of 20 bulbs are faulty. The probability is calculated as 4/20, simplifying to 1/5. Probability of drawing a good bulb after a non-defective one is removed (1:24-3:15): The video presents a scenario where a non-defective bulb is drawn first and not replaced. The instructor then explains how to calculate the probability of drawing another good bulb from the remaining 19 bulbs, with 15 good bulbs left, resulting in a probability of 15/19. Probability with numbered discs (4:00-10:36): The video moves on to a problem involving 90 discs numbered 1 to 90. Probability of a two-digit number (4:08-6:52): The instructor explains how to find the number of two-digit numbers (81 out of 90) and calculates the probability as 81/90, simplifying to 9/10. Probability of a perfect square number (7:00-8:35): The video lists perfect square numbers between 1 and 90 (1, 4, 9, 16, 25, 36, 49, 64, 81) and calculates the probability of drawing one as 9/90, or 1/10. Probability of a number divisible by five (8:37-10:36): The instructor identifies numbers divisible by five within the range (5, 10, ..., 90) and determines there are 18 such numbers. The probability is then calculated as 18/90, simplifying to 1/5.
