Suppose a brewery has a filling machine that fills 12 ounce bottles of beer. It is known that the amount of beerpoured by this filling machine follows a normal distribution with a mean of 13.14 onces and a standarddeviation of 0.04 ounce. Find the probability that the bottle contains more than 13.14 ounces of beer.

B) 1
C) 0
D) 0.4
