If X and Y are sets of integers, X # Y denotes the set of integers that belong to set X or set Y, but not both. If X consists of 14 integers, Y consists of 18 integers, and 6 of the integers are in both X and Y, then X # Y consists of how many integers?
Choose the correct option:
A) 6 B) 16 C) 20 D) 30 E) 174
The number of integers that belong to set X ONLY is 14-6=

<output>12</output>
12;   The number of integers that belong to set X or set Y, but not both is   8+12= 
<gadget id="calculator">  8+12</gadget>
<output>20</output>
20.   Answer: 20.
