It depends on the number of possibilities for each number, a piece of information that you did not provide. Please restate the question.

The generalized answer, however, is 1 in the number of combinations of N things taken M at a time, M in this case being 7, and that number is N! / (M! (M-N)!).

As an example, if M were 50, then the number of combinations of 50 things taken 7 at a time is 50*49*48*47*46*45*44/7/6/5/4/3/2, or 99,884,400. In this case, the odds would be 1 in 99,884,400 or about 0.000000010011573379.
