In the old days, we could buy 8 inch floppies for our computers on which to store our favorite programs and data. But, the manufacturing ability was not that good back then and 1% of these 8 inch floppies sold had a bad sector or two on them which made them have less memory space. If your company bought 1000 8 inch floppies for data storage and backup, what is the chance that none of them have a bad sector? Use the normal approximation to the binomial to calculate this probability. Remember, all probabilities are taken to 4 decimal places for this class
