Answer: At least 4/14 = 28.5%
Step-by-step explanation:
Select the location of a math book at the far end. The probability that the book next to it is a math book:
4 remaining math books, out of the 14 remaining books
In the middle, there are two potential spots adjacent to each book, so it could be higher - that’s why I say “at least” 4/14
