Combinatorics? Lottery, Canadians help?

    1. The problem statement, all variables and given/known data

    My professor gave us this problem, I asked him about it but he just dumped it on me by saying "check it out yourself".

    Problem

    Determine the number of all combinations of winning numbers for Lotto 6/49

    3. The attempt at a solution

    I read on wikia there are actually 5 numbers? I am not sure if they repeat...if it even matters from a set of 49.

    So my guess is

    [tex]\binom{49}{6} = \frac{49!}{6!(49-6)!} = \frac{49 \cdot48 \cdot 47 \cdot 46 \cdot45 \cdot44}{6\cdot5 \cdot4\cdot3\cdot1} = 13983816[/tex]

    What's the problem? I don't know if 0 is in the set...
