Question: Radio frequency identification (RFID) is an electronic scanning technology that can be used to identify items in a number of ways. One advantage of RFID is that it can eliminate the need to manually count inventory, which can help improve inventory management. The technology is not infallible, however, and sometimes errors occur when items are scanned. If the probability that a scanning error occurs is 0.0065, use either Excel or Minitab to find

a. the probability that exactly 20 items will be scanned incorrectly from the next 5,000 items scanned

b. the probability that more than 20 items will be scanned incorrectly from the next 5,000 items scanned

c. the probability that the number of items scanned incorrectly is between 10 and 25 from the next 5,000 items scanned

d. the expected number of items scanned incorrectly from the next 5,000 items scanned
