We solved some examples related to the joint distribution function. Then we started to discuss about sample statistics and their distribution introducing the central limit theorem.

We looked at the exercises from the homework. We discussed properties of the joint probability function for the continuous random variables. We looked at a portfolio example with the interest in calculating the mean and the variance of the portfolio.

We discussed the homework. We introduced discrete random variables, and a few distributions: bernoulli, binomial, hypergeometric and Poisson. We also discussed about the joint probability distribution, mean, variance and covariance of a random variable or a linear function of a random variable. We looked at an application about mean/variance of a portfolio.
