2.2.6A car panel is spray-painted by a machine, and the technicians are particularly interestedin the thickness of the resulting paint layer. Suppose that the random variable X measuresthe thickness of the paint in millimeters at a randomly chosen point on a randomly chosencar panel, and that X takes values between 0.125 and 0.5 mm with a probability densityfunction off(x) = A(0.5 - (x - 0.25)²)for 0.125 ≤x≤ 0.5 and f(x) = 0 elsewhere.(a) Find the value of A and sketch the probability density function.(b) Construct and sketch the cumulative distribution function.(c) What is the probability that the paint thickness at a particular point is less than 0.2 mm?
