-It takes a while to run this simulation to determine an approximate value for π.  Write a program using a ''for'' loop or a ''while'' loop that can run 100,000 dart throws more quickly. +It takes a while to run this simulation to determine an approximate value for π.  Write a simple text only program that uses a ''for'' loop or a ''while'' loop so that can run 200,000 dart throws more quickly the the graphical version
  
 This works since the ratio of the Area of a circle divided by the Area of the square is pi*r^2 / (2r)^2 = pi/4. The ratio of the darts that land in the circle divided by the darts thrown on the square should be the same ratio, pi/4 (if we throw enough random darts!). So 4 times this proportion is pi! This works since the ratio of the Area of a circle divided by the Area of the square is pi*r^2 / (2r)^2 = pi/4.
