In the evaluation of a sales training program, a firm discovered that 42 of its 120 salespeople received a bonus last year but that 17 of those who received a bonus had not attended the sales training program. If 40% of all the salespeople attended the training program, find the probability that a randomly selected salesperson who did not attend the training program did not receive a bonus. Express your answer in decimal form (not percentage form) and round it to 3 decimal places.
