In a semiconductor manufacturing process, three wafers from a lot are tested. Each wafer is classified as pass or fail. Assume that the probability that a wafer passes the test is 0.7 and that wafers are independent. Determine the probability mass function of the number of wafers from a lot that pass the test. Round your answers to three decimal places (e.g. 98.765). PIX = 0) = i PIX = 1) = i PIX = 2) = i PIX = 3) = Statistical Tables and Charts eTextbook and Media Save for Later
