The concepts of grey probability, grey probability distribution, grey probability density, grey expectation and grey variance are defined based on the theory of probability and grey system approach. The method of grey\|stochastic risk for system risk analysis is established. In this method, the uncertainty of system risk is attributed to grey uncertainty of system, the variables of system performance function are treated with grey probability distributions and the system hazard is quantified with grey\|stochastic risk. The grey\|stochastic risk can be transformed into ordinary stochastic risk and computed using advanced first\|order second\|moment method. An example of application is given.
