3. Suppose that the CDF of a random variable X is given by F(x) = 1 e3x for x 0, and 0 otherwise. a.) Find the PDF of X. (Be sure to include the domain.) f(x) = d/dx F(x) d/dx (1- -3x) = 3x = 3e for x 70 and 0 Murrwise b.) What is P(X > 3)? c.) What is P(X = 3)? 05 d.) What is the 70th percentile of X? 3.
