Monte carlo implementation. Running the simulation over random values of inital velocity and angle and height, to display the probabilities of different range values. This shows how likely the projectile will land at a certain area, which can be set as an target. This is important since projectile motion is never the same, even with same parameters, practically, it will not land exactly at the same spot, mainly because of shifting environments such as air resistance. So calculating ranges for different inital parameters(close to a certain mean) helps identify where the projectile may land(never 100% certain)
