An irregular die is rolled. Let X be the number of pips on the top face. The Question 5 probability function (pf) of X, f(x) = P(X = x) is given by the following table: %3D 1 3 4 5 f(x) 0.25k2 0.15 0.2k 0.1 0.2k 0.1k (a) Find the value of k that makes this a valid probability function. (b) Graph the cumulative distribution function (cdf) F(x) = P(X < x) for all r.
