We notice that the time-symmetry of stochastic processes plays an essential role in the generalization. The approach of the theory of quantum stochastic processes restricts our investigation to the timesymmetry of stochastic processes, while the interpretational problems of quantum mechanics are so chaotic that we can not specify the problems. The subjective probability, which represents our ignorance on the deterministic world, is a timeasymmetrical prediction either from the past to the future or from the future to the past, and satisfies the additivity of probability. We first doubt the time-asymmetry of objective stochastic processes which stochastic processes have been supposed to have. Then, necessarily we are forced to doubt the additivity, too. The timesymmetry of objective stochastic processes mentioned above leads to the conclusion that the strangeness of quantum mechanics is not the strange-ness of mechanical parts of quantum mechanics. The quantum mechanical strangeness results from our biased view about the concept of probability. Finally, an answer to the question whether or not quantum stochastic processes are classically mechanical is given.
