What is the rule for probabilities with a deck of cards? Are there specific rules for getting "At most" 1 diamond or "At least" one king?
----
ANY "at least 1" problem makes use of the complement Rule.
---
P(at least one success) + P(no successes) = 1
---
Therefore:
Rule: P(at one success) = 1 - P(no successes)
===========================================
So,
P(at least one king) = 1 - P(no kings)
========================================
But,
P(at most 1 diamond) = P(no diamonds) + P(1 diamond)
=========================================================
