If the sample contains any defective games, the entire lot is rejected. What is the probability that a lot containing exactly 2 defective games will still be shipped? (Round your answer to three decimal places.)

P (defective piece) = 2/36

P (selected piece) = 8/36

P (selected and defective) = 2/36 x 8/36

= 16/1296

= 1/81
