A fingerprint verification system requires a user to provide five usable fingerprint images for enrollment and three usable fingerprint images for verifcation.

Enrollment stage: A user provides five fingerprint images, which are all accepted by the system, and thereby completes the enrollment.

Verification stage: The user provides three fingerprint samples, which results in three similarity scores. The combination of the three scores is used to make a decision about the identity of the user.

What is the sum of the numbers of presentations, attempt$($s$),$ and transaction$($s$)$ during enrollment?
