# Distribution Function of a Random Variable

A random variable X follows a distribution with probability density function

(f_x)(x) = kx(1 - x), 0 < x < 1.

(i) Determine the value of k.

(ii) Find the probability P(0.4 <= x < 1)

(iii) Find the value of a such that the cumulative density function F(a) = 0.6
