[math-fun] “Random” cards

I suspect there is a strong cultural component to this. Different cultures have very different notions of "lucky" vs. "unlucky" numbers, for instance. Even within a culture, age probably plays a factor as well. Tom James Propp writes:

If you ask people to name a random card in a standard deck, what regularities govern their answers?

(Is this something someone has looked at?)

Cf. the observation that when people are asked to pick a number between 1 and 20, the most common answer is 17.
