A nut bolt with a circular opening is rejected if its diameter is greater than 2.01 cm or less than 1.97 cm. What is the expected number of rejected nut bolts if the diameter in a batch of 15 000 bolts are normally distributed with a mean of 2.00 cm and a standard deviation of 0.01 cm? Numerical 14.
