Answer: The fifth piece of paper could have any number 9 and less or 14 and greater. 
Step-by-step explanation:  The list of choices is not given in the question, but it makes sense that the new number would not be a duplicate of any of the numbers 10, 11, 12, 13. Otherwise that would change the probability to 5/5. 
So any other number could be a possibility.
