Accepted Solution

A:

25 - total students
16 - total tired
6 - tired and hungry
3 - tired and happy
2 - tired, happy and hungry
16 - 6 - 3 - 2 = 5 ONLY tired.
10 - total happy
3 - happy and tired
2 - happy and hungry
2 - happy, tired, and hungry
10 - 3 - 2 - 2 = 3 ONLY happy
add up what we have..
5 only tired
3 only happy
3 happy and tired
2 happy and hungry
6 tired and hungry
2 happy, tired, and hungry
5+3+3+2+6+2 = 21
there's 25 students total, so
25 - 21 = 4 student ONLY hungry.
