Let X be a random variable with CDF Fx (x)=x³ for 0 ≤ x ≤ 1. Find: a) P (X > ¹); b) the density function fx (x); c) E(X). d) Let Y₁, Y2, Y3 be three points chosen independently and uniformly on the unit interval [0, 1], and let X be the rightmost point of them. Show that X has the distribution described above.
