Problem Statement:
The pre-placed blocks will ask you how many points you want to animate, will randomly place them, then tell you how many are in the black area. Play around with the program to learn more about the probability of random events. What is the chance any given point will be in the black area? If you know this, estimate how many points will be in the black area if you input 100 points. How about 300 points?
