WebLet X be a continuous random variable whose probability density function is: f ( x) = 3 x 2, 0 < x < 1 First, note again that f ( x) ≠ P ( X = x). For example, f ( 0.9) = 3 ( 0.9) 2 = 2.43, which is clearly not a probability! In the continuous case, f ( x) is instead the height of the curve at X = x, so that the total area under the curve is 1.
