The Suspect Pool

Difficulty: easy

Detective Quacker looks up from the missing presents report with determination. Now that we know the scope of this heist, we need to find who could access the warehouse. Not everyone could pull off this heist! The warehouse requires high-level access clearance. Find all volunteers with experience_level of 7 or higher - these ducks had the keys to everything. We need to know how many potential suspects were dealing with!

Your task

Count how many volunteers have an experience_level of 7 or higher. You will be working with the `volunteer_ducks` table.
