   Nota:

   • ExEy f(x,y) = 1
2. MPF -Marginal probability function
3. Mathematical expectation

5. Standard Deviation

1. PMF - Probability mass function
2. MPF -Marginal probability function

Nota:

• f(y/x) = f(x,y)/f(x) = (Joint probability function)/(Marginal Probability distribution function of x)
