I created this question to serve as a fool me once question, since I find that some students don't spot the hidden clue in the words "or both"
If every student is either a freshman, a baseball player, OR BOTH, then this means there are ZERO students who are neither freshman nor baseball players.
So, if you're applying the overlapping sets formula Group 1 + Group 2 - Both + Neither = Total, then you now know that NEITHER = 0
Alternatively, if you're using the Double Matrix approach, you can now add a zero to the bottom-right box to get this ...
And, from here the remaining boxes are easy to complete...
.... We can see the correct answer is C
Here's a video lesson on the Double Matrix method:
