Properties of the Normal Curve Known characteristics of the normal curve make it possible to estimate the probability of  occurrence of any value of a normally distributed variable. Suppose that the total area  under the curve is defined to be 1. You can multiply that number by 100 and say there is  a 100 percent chance that any value you can name will be somewhere in the  distribution. (  Remember   : The distribution extends to infinity in both directions.)  Similarly, because half the area of the curve is below the mean and half is above it, you  can say that there is a 50 percent chance that a randomly chosen value will be above  the mean and the same chance that it will be below it.
