Step-by-step explanation:
Given : The amounts a soft drink machine is designed to dispense for each drink are normally distributed, with mean 
Standard deviation : 
z-score : 
For X = 11.5
For X = 11.6
Now, the probability that the drink is between 11.511.5 and 11.611.6 fluid ounces will be :-
Hence, the probability that the drink is between 11.511.5 and 11.611.6 fluid ounces =0.1499
