Again, that depends on how you look at the card. Cups and Pentacles are both passive suits, so if you look at the card from that standpoint, the answer would be no. But 9s are another completion of a cycle, so numerologically you could say yes. Looking at the imagery in RWS-style decks, you could also say yes.
None of those approaches is better or worse for doing a 1 card answer. My point is that there are multiple approaches for how a single card can be used to judge the likelihood of something occurring (as opposed to using a single card to provide information or insight on something). And for me, YMMV, I would have to know which approach I'd use before I drew any cards.
