“Risk” is an important and significant word that denotes the root of a serious problem symbolizing modern society. The meaning of this word suggests a basic approach to the probable resolution of its difficulties, and its study consequently assures the wholesome future of the world. The concept of risk is neither a simple concept of “danger or hazard” nor of “loss or cost”. But it is the complex concept of behavior or choice of action itself that leads to perilous situations, ruinous consequences, and a damaging sequence of events.
