The probability density function (PDF) of a sum of two independent continuous random variables X and Y is given by the convolution of the PDFS, fx and fy: fx+r(2) = | fx(x)fv(z – x) dx. -00 Show that a sum of two independent standard normal variables results in a normal variable. Find the PDF of such a sum. Give your solutions in two ways: 1) by using the convolution function above; 2) by using moment generating functions.

Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
