A force of at least 1900N (Newtons) is required to initially push a large object from its state of rest. The amount of pushing force that a human can exert is described by a normal distribution with mean 575N and standard deviation 125N. If three randomly selected individuals are asked to push this large object together, what is the probability that their combined effort will cause it to move?
