JEE Main Mathematics

Statistics and Probability

Ask anything about Statistics and Probability (JEE Main Mathematics): a concept you are stuck on, or a problem to work through step by step.

Ask any maths question, or type an equation like x² − 4x + 3 = 0

Enter sends, Shift + Enter adds a line. Type / for a fraction and ^ for a power, or press + for the maths keyboard, a photo scan and more.

A timed sectional mock on this unit

Mean, median, mode, mean deviation, variance and standard deviation; the probability of events, the addition and multiplication theorems, Bayes' theorem and probability distributions.

Key formula

\sigma^2 = \frac{1}{n}\sum (x_i - \bar{x})^2, \quad P(A_i \mid B) = \frac{P(A_i)\,P(B \mid A_i)}{\sum_j P(A_j)\,P(B \mid A_j)}
