5 players see a flop (Hold'em)...

[Kristian]

5 players see a flop. The flop has 2 spades. What is the probability that at least one of the 5 players holds 2 spades?

Chance of 1 player holding 2 spades is 5,09% (easy), but already by the 2nd players the calculations becomes tough, since you have to account for a possible spade in previous players hand.

I can't think of a clever way to calculate this.
