Electronic baseball games manufactured by Tempco Electronics are shipped in lots of 36. Before shipping, a quality-control inspector randomly selects a sample of 7 from each lot for testing. If the sample contains any defective games, the entire lot is rejected. What is the probability that a lot containing exactly 3 defective games will still be shipped? (Round your answer to three decimal places.)
