3. The Pareto distribution is a common probability distribution for describing quantities thatfollow so-called power laws (e.g., maximum one-day rainfall totals in different locations, thesizes of files transmitted via the Internet, etc.). Here we will use calculus again to learn a bitmore about this distribution.a) Suppose you were given the cdf for this distribution:x < Xmin0,F(x)(Xmin`,х > ХminхDifferentiate the cdf with respect to x to obtain the pdf. [You can check your answer bylooking on Wikipedia.]b) Assuming that a > 1, show that the mean/expected value of this distribution is given by:αχminE(X) :a – 1
