There are 10 teachers, 4 teach french, and the others teach spanish or german. If you can only selected 3 teacher, how many combinations are there?

[spoiler]the answer is 100, please tell me how and why! thanks so much

actually the question posted here is incomplete as it is missing "at least one must teach french"
in that case the question is to select 3 teachers from 10 which is
10C3 = 120

otherwise if at least one french teacher is to be selected then the above solution is perfect :-)
