* Select the number $(1,\ 2$, ... $)$ of the task to be processed. The number "0" corresponds to a "Reset": Setting as at the program start. * A task description is displayed. Parameter values are adjusted. Solution after pressing "Sample solution". * In the task description, we use $\rho$ instead of $\rho_{XY}$. * For the one-dimensional Gaussian PDF holds: $f_{X}(x) = \sqrt{1/(2\pi \cdot \sigma_X^2)} \cdot {\rm e}^{-x^2/(2 \hspace{0.05cm}\cdot \hspace{0.05cm} \sigma_X^2)}$.
