In JEE Main 2026, Probability in the Mathematics section has a small but consistent weightage, usually contributing about 3-3.3 % of the total Maths paper.
When combined with Statistics, the broader Probability & Statistics area can contribute around 3-6 % weightage overall, totalling around 9-12 probability questions.
The basic probability questions include Random experiments, sample space, events, and axioms of probability.
Focus on formulas and concepts like Bayes' theorem and conditional probability; you can solve JEE Main questions from this chapter in under 5 minutes.
