I've been stuck on this question for some bit now. Im not sure whats wrong with my code. Can i get some help Please?

Heres the code that I've been using:

SELECT * COUNT (DISTINCT genre) "Science Fiction" AS scifi_book_count FROM books;

You're not concerned with distinct values, and even if you were, you are trying to retrieve the count of distinct genres (and that is not the right syntax for that, either), not the count of books in that genre. You want to count all the books where the genre is "Science Fiction", so you would do it like this:

SELECT COUNT(*) AS scifi_book_count FROM books where genre = "Science Fiction";
