Question:

(a) For what value of α > 0 is the function

f(x) = αx^-2u(x - α)

a probability-density function? Use a sketch to illustrate your reasoning and recall that a pdf has to integrate to one. [u(x) is the unit step function.]
(b) Find the corresponding cumulative-distribution function.
(c) Compute P(X ≥ 10).
