So, from what I've found when finding the domain and range of a table the domain is all the values on the left (x values) and the range is all the values on the right (y values). So the domain for this graph is {0,5,9,32} and the range is {3,4,2,7}. Hopefully I understand this correctly and helped you.
There is an 8/20 chance that the next person will receive a window seat. You simplify that probability to get your answer. 8/20 becomes 2/5. So the answer is 2/5.
