Discrete random variables

Distributions & Random Variables

Discrete random variables taking a finite set of values, with probability distributions in tables or as expressions where probabilities sum to 1, and finding \(E(X)\), \(\mathrm{Var}(X)\), standard deviation, fair games, and linear transformations \(E(aX+b)=aE(X)+b\), \(\mathrm{Var}(aX+b)=a^2\mathrm{Var}(X)\).
