Ralph has a higher chance of hitting the ground first.
Two construction workers are working on top of a building. The building is 200 meters high. The first construction worker, Ralph, is 150 meters high. The second construction worker, Tim, is only 100 meters high. If both construction workers fall at the same time, but Ralph falls at a speed of 20 meters per second, and Tim falls at a speed of 15 meters per second, who has a higher probability of hitting the ground first?
