![]() ![]() The exact shape of the curve is given by a complicated formula that you do NOT need to know. Statistically speaking, it is a probability distribution for a continuous random variable: The ordinate represents the probability density for the occurrence of a value. The normal curve is a mathematical formula that assigns probabilities to the occurrence of rare events. This would be an extremely rare event, but it is conceivable. In an infinite amount of time, a random process could ultimately generate structured results: e.g., a group of monkeys seated at typewriters could peck out all the great works of literature. What is a "normal" distribution? The distribution of equally-likely events in the long run through accidents of nature.
