(a) Fewer than 239
The probability that fewer than 239 parts are defective is
(Round to four decimal places as needed.)
(b) More than 263
The probability more than 263 are defective is

Suppose that 30 percent of the bottles produced in a certain
plant are defective. If a bottle is defective, the probability is
0.9 that an inspector will notice it and remove it from the filling
