Random walk, in probability theory, a process for determining the probable location of a point subject to random motions, given the probabilities (the same at each step) of moving some distance in some direction. Random walks are an example of Markov processes, in which future behaviour is Random walks in more than one dimension . Of course the 1-dimensional random walk is easy to understand, but not as commonly found in nature as the 2D and 3D random walk, in which an object is free to move along a 2D plane or a 3D space instead of a 1D line (think of gas particles bouncing around in a room, able to move in 3D). The walker could accomplish this by tossing a coin with probability of heads \(p\) at each step, to determine whether to move right or move left. Other types of random walks, and additional properties of this random walk, are studied in the chapter on Markov Chains.
