WebThe probability for the continuous distribution is defined as the integral of the density function over some range (adding up the area below the curve) The integral at a point is zero, but the density is non-zero. WebThe probability density function is nonnegative everywhere, and the area under the entire curve is equal to 1. The terms probability distribution function and probability function have also sometimes been used to denote the probability density function. However, this use is not standard among probabilists and statisticians.
