Basics (2) - S3-E1
Corrected entry: In the second part of this episode, the Doctor asks the ship's computer of how many persons are on board to get an idea of the number of invading Kazon he is facing. The ship responds with "89 Kazon and one Betazoid". It fails to mention Seska who is a Cardassian.
Correction: The Computer obviously registered Seska as Kazon.
