Joint Probability Distributions
Cards in this deck (10)
- 1E(X+Y)=E(X)+E(Y)
- 2E(X-Y)=E(X)-E(Y)
- 3E(aX+bY) =aE(X)+bE(Y)
- 4If X & Y are independent E(XY)=E(X)E(Y)
this does not mean that X & Y are independent! - 5E(X^2Y)=E(X^2)E(Y)
- 6E(X/Y)=E(X)E(1/Y)
- 7Var(X+Y)=Var(X)+Var(Y)
- 8Var(X-Y)=Var(X)-Var(Y)
- 9Var(XY)=E(X^2)E(Y^2)-E^2(XY)
- 10Var(aX±bY)=a^2Var(X)+b^2Var(Y)
