Suppose that X is a random variable with probability density function given by: fx(x) = { k(x^3 + x), 0 ? x ? 2; 0, otherwise. (Note that you must determine the value of the constant k in part 1 below and use it in all subsequent parts of this problem.) 1. Calculate the value of k so that fx is a valid probability density function. (2 pts)
