13. Let X equal the number of widgets that are defective when 3 widgets are randomly chosen and observed. The possible values for X are {0,1,2,3}. The probability Mass Function for X, Compute for Cumulative Distribution Function PMF ANSWER: CDF P (X = x) or f(x) P(X < x) = F(x) P(< 0) = F(0) P(< 1) = F(1) P(< 2) = F(2) P(< 3) = F(3) 0.550 1 0.250 2 0.175 3 0.025
