As Rich has pointed out in different language, you may be having a semantic problem. The following expressions may sometimes be equivalent in adjacent pairs, but not all four are equivalent: (a) drawing at least one king (b) drawing a king at least once (c) drawing a particular king at least once (d) drawing the King of Diamonds at least once
You have supplied a correct answer to (c) or (d). This is not how I would understand (a), which is the language used in the problem.
