A safe is randomly assigned a four-digit code. The company selling the safe sponsors a contest whereby contestants pick four digits (0 through 9) to make a 4-digit code. If the code opens the safe, the contestant wins $400$400. Otherwise, the contestant wins nothing. Let XX be the random variable defined by the amount of money a contestant wins by picking one code. How many distinct values of XX are there? Find the probability density function of XX (Note: Please write the values of XX in ascending order!).
