We mentioned the risk in the preface, let us define it. The risk is a possibility of deviation from the expected state outcome, value. The risk, in contrast to uncertainty, can be measured by probability, e. The uncertainty means that we do not know what will happen the future is roulette and we do not know or we are unable positive determine expected probabilities of events.

A little more theory and we can follow the exhibits below. The expected value EV is a weighted average of all possible outcomeswhereas the weights are represented by probabilities.

The expected value is a mean value, not necessarily the most probable outcome! The general formula of the expected valueEVis loss following:. The expected value can be roulette positive and negative.
