Probability — JEE Questions, Notes & Weightage
Class 11 & 12 Statistics & Probability NEET weightage: High 1,262 questions
Class 11 covers classical probability and the addition theorem; Class 12 adds conditional probability, Bayes' theorem, independent events, and probability distributions (including the binomial distribution). Counting-based classical-probability problems and Bayes'-theorem numericals are both tested constantly in JEE.

How is this chapter connected to Permutations and Combinations?
Most classical-probability questions are counting problems in disguise — finding favourable outcomes over total outcomes using the same permutation/combination techniques.
Why is Bayes' theorem considered the hardest part?
It requires correctly identifying which events are the 'causes' and which is the observed outcome before applying the formula — a setup error here is more common than a calculation error.
