Continuous Random Variable and Probability Density Function

Let X denote a continuous random variable with probability density function f(x) = kx^3/15 for 1≤ X ≤ 2.

a. Determine the value of the constant k.

b. Determine the probability that X > 1.5.

c. Determine the cumulative distribution function F(x) and state the values of F(x) at x = 0.5, 1.5, and 2.5.
