The probability of duplicates using random numbers goes up rapidly
with large numbers of cards, just as the amusingly high probability
that in any class room 2 people will have the same birthday.
But it is probably much higher still if you are using a bunch of cards
from the same manufacturer that didn't bother to make them unique. ;)
