How many countries do not have an roller coaster longer than 3000?
SELECT COUNT(*) FROM country WHERE NOT country_id IN (SELECT country_id FROM roller_coaster WHERE length > 3000)
SELECT COUNT(*) FROM "country" WHERE NOT "country_id" IN (SELECT "country_id" FROM "roller_coaster" WHERE "length" > 3000)
