irreversible mirror image

In probability theory, a stochastic process, or sometimes random process, is the counterpart to a deterministic process . Instead of dealing with only one possible way the process might develop over time , in a stochastic or random process there is some indeterminacy described by probability distributions. This means that even if the initial condition is known, there are many possibilities the process might go to, but some paths may be more probable and others less so.
