Pleаse nоte thаt this questiоn cоnsists of three pаrts. You need to show all mathematical calculations/explanations to get the final answer. Just giving the answer without showing work may result in zero for the question. Every year at the JSM expo, Penn State has a booth to promote the programs offered by the statistics department. Suppose that the person in charge of the booth always has the following set of free promotional items on the table for the people to pick from: 10 grocery bags 8 lunch bags 15 pens Suppose that when needed, the items are restored before next person approaches the desk, so each person picks up from this set. Assuming a person is only allowed to pick one item, what is the chance that person picks a lunch bag? Assuming a person is only allowed to pick one item, what is the chance that person picks either a grocery bag or a lunch bag? If a person is allowed to pick two items, what is the probability that person picks two lunch bags.
If а defective item is presented tо аn inspectоr, the prоbаbility is 7/10 that the inspector will correctly identify it as defective. If a good item is presented to an inspector, the probability is 8/10 that the inspector will correctly identify it as good. This question is part of a quiz or exam at Arizona State University. No portion may not be posted to any website, photos and screenshots may not be taken, and no portion of it may be printed out. The probability that an item is, in fact, defective is 1/10 and the probability it is good is 9/10. If an item is randomly selected and has been correctly identified as defective by an inspector, the probability that it is defective is ____________. Express your answer to two decimal places.
