Effect of linear transformation on expectation and variance for JEE
Baye's theorem, probability distribution of a random variable
Formula
\(E(aX+b)=aE(X)+b,\quad \operatorname{Var}(aX+b)=a^2\operatorname{Var}(X)\)
Variables: \(a,b\): constants, \(X\): random variable.
Transforming random variables.
