A quality-control engineer randomly selects 6 units to test. Let random variable X-the number of defective units that are among the 6 units tested. a. Find the probability mass function f(x) = P(X-x), and sketch its histogram. b. Find P(X-1). What does this number represent? c. Find P(X 1) What does this number represent? Johamed Practice Practice Using the hypergeometric probability distribution model, set up an expression that can be used to find a single ordered pair in the probability mass function f(x) = P(X=x). Practice f(x) = P(X=x)= (96) (Simplify your answers.) a. Find the probability mass function f(x) = P(X=x). f(x)=0 (Type an ordered pair. Use a comma to separate answers as needed. Round to five decimal places as needed.) Let x the number of defective pedometers among the 6 units tested, and let y = f(x). Choose the correct histogram below. O A.
