Theory. Distribution law of a two-dimensional discrete random vector in a tabular form; independent random variables, interpretation of correlation coefficient value (are random variables correlated?). 1. Discrete random vector law is given. Check if variables are independent. -1 0.2 0.3 0.1 0.4 2. Which statement is true? a) If the variables are independent, they are uncorrelated (correlation coefficient is o). b) If correlation coefficient is O, the variables are independent.
