WebStatistics and Probability questions and answers. For 0 ≤ x ≤ 1 let f (x) = kx (1 − x), where k is a constant. Find the value of k such that f is a density function and find the cumulative distribution for the previous density function. Do I need to integrate kx (1-x) from 0 to 1 and set it equal to 0 to find k, is that correct? http://www.ams.sunysb.edu/~jsbm/courses/311/examples-joint-pdfs-sol.pdf lenawee golf club
