The Total Area Under A Probability Density Curve

The Total Area Under A Probability Density Curve. The normal distribution is a probability distribution, so the total area under the curve is always 1 or 100%. For example, if the mean (average) male height is 5'10 then there is a 50% chance that a randomly selected male will have a height that is below or exactly 5'10.
