Consider $\binom{13}{2} \binom43 \binom41$ where $13$ is the number of ranks and $4$ is the number of suits in a standard $52$ card deck.
One possible $2$-set out of thirteen ranks is $\{2, 3\}.$ Then for the first card we choose three suits and for each one of those we choose one suit. But which one of $\{2, 3\}$ is the first card and which one is the second card?
