There are 4 books.
The math book can either be top, second from top, third from top, or on the bottom.
The probability of being in any single given position is 1/4 = 25% .
Since each book can be put on the top, and there are 4 books, the chances of a math book going on the top is 1/4, while the other 3 chances are the other books. So your answer is 1/4 or 0.25
