MATH 215-A machine used in a production process is set
A machine used in a production process is set up correctly 97% of the time.Given that the machine is set up correctly, only 5% of the items it produces are defective, while 95% are not defective. On the other hand, if the machine is set up incorrectly, 60% of the items it produces are defective,while only 40% are not defective.What is the probability that a randomly selected item from the production process will not be defective? 5 marksAlso construct a tree diagram.Note: Express probabilities to 4 decimal places of accuracy.***Question 6 In a survey of 100 business executives, 60 per cent were male and 40 percent were female. Seventy per cent of the male executives used a PDA(personal digital assistant). Overall, 60 per cent of the executives used a PDA. Construct a two-way classification table for the survey results.
