Here is one way to think about a mixed random variable. Suppose that we have a discrete random variable X d with (generalized) PDF and CDF f d ( x) and F d ( x), and a continuous random variable X c with PDF and CDF f c ( x) and F c ( x). Now we create a new random variable X in the following way. church supplies candles
