The probability density function of the sum of random variables and marginal density function are important and difficult concepts in the course of probability theory. The key to calculate them is to determine the range of interested variables and integral variables. Combined with graphics, the range of those variables can be determined quickly by using projection threading method. The proposed method is intuitive and easy to master.
