Actually the dictionary defines random as a thing done or said without thinking of the consequences and with no definite plan or pattern. This means that many of the things dissmissed as not being random within the 9 pages of its definition on this website, are in fact random. In fact those who believe in the theory of the big bang have to acknowledge a certain degree of randomness exists in everything that humans do, simply because there is no "definite plan" and we make our own decisions. Therefore, in the context of the universe, a man taking the train on his way to work in the morning can be seen as random. In the same way as university students deciding to go to a 24 hour tesco at 6am is random as it is a decision made without thinking of any consequences.
I am writing this definition without a definite plan and i am not thinking of any consequences as it is a decision i have made on the spot. Therefore, it is to a certain extent, random.
