Now, we shall examine how well this model of two-person zero-sum game fits to human life. Human life is full of actions and at every step we have to decide which one of the various alternative choices of action suits us best. If the outcome of each choice is predictable in advance, the problem of decision making is quite simple as we can choose the action with most favorable outcome according to our criterion of preference. How- ever, the things in real life are not so simple. The outcomes of our actions are mostly uncertain. We have to live and make decisions in the face of uncertainties. Every uncertainty involves risk (which may be statistically defined as long term average loss). Nobody wants to run a risk and yet it is inevitable with uncertainty. We can, however, try to control or minimize this risk by taking the right decision.
