Suppose that the game contains 52 cards (If that is not the case,
remplace the 52 number by the number of the cards in the game,
and do the same reasoning as below)
First drawing we have 52 possibilities.
Second drawing there remains 52-1 possibilities (since we have already drawn one card).
Proceeding as before we get the number of the whole possibilities:
[tex]52\times51\times50\times49\times48[/tex]
