Grade 12 data management help?
There are 10 players on the basketball team, 12 players on the volleyball team, and 15 members of the track team. Of those players, 2 athletes are on all three teams. How many committees of 4 players can be formed if there must be at least 1 member from each team represented? Order doesn't matter.
The answer is 24 015. I have no idea how to do this question. We are supposed to use nCr with cases apparently.

@mush727: I'm in pre-calc grade 11 and I see what kind of method you're supposed to use but I don't know where to start.
Data becomes a lot easier after this permutation and combination unit.

Believe it or not this was a test question from my current data teacher from last semester. I got the test from my friend, idk how she expects anyone to get this question. We've never done anything this complicated.
