I think this question is being marked incorrectly. SELECT COUNT(platform) FROM games; Should return 4, as the keyword DISTINCT isn't used. However, it's saying this is the incorrect answer. Could you please check?

Without the DISTINCT keyword it will count all non-null values. In this case, out of the 4 rows, 2 of them have null values in the platform column. So there are 2 non-null values.
