Calculate Probabilities with Random Data Sets
Problem Statement:
The board blocks will generate a blue and red area. When you run the program It will place 100 points randomly on the grid and ask you some questions about the likelihood of the points being placed in specific places.

#include <chplot.h>

scanf("%lf", &probAns);
printf("If 100 points get placed randomly on the grid, how many would you expect to land in the blue area? Please round answer to nearest whole number. "+"\n");
scanf("%lf", &blueAns);

printf("If the number of points that landed in the blue area was different from what you predicted, are you surprised? If the amount of points is the same as your prediction, would you expect this result to happen every time? (Please input yes or no)"+"\n");
