Suppose that N = 12 resistor have just come off the production line. Also assume that a = 3 are defective (have serious defects). Thus b = 9 are defect-free. A sample of n = 5 are selected and tested to see if they are defective. Let X = the number defective refrigerator in the sample (?:{0,1,2,3}). a) Find the probability mass function of X and draw its graph. b) Find the expected value of the defective refrigerator for this case (i.e. in the case with 12 refrigerators have produced in a line)
