Question 3. Part (a) Determine the equation for the Cumulative Density F() for the Laplacian PDF defined with unit variance and zero mean. Hint. the absolute value means that the equation has to be split into two halves. Let the CDF integrals be of the form f x and Jo". Part (b) Plot the PDF and CDF from the preceding problem. Part (c) Repeat the above calculations, but with generic mean and variance.
