WebThe graph of a continuous probability distribution is a curve. Probability is represented by the area under the curve. The curve is called the probability density function (abbreviated as pdf). We use the symbol f(x) to represent the curve. f(x) is the function that corresponds to the graph; we use the density function f(x) to draw the graph of ...
