The sentence '6000 people read either the Herald or the Tribune. ' tells us that there are three groups.. only herald, only tribune, and both.
Combined.. statements give us only herald and only tribune ..
So the third group can be found by subtracting the two groups.. both =6000-2000-2500=1500.

What about the group that does not read either newspaper?
In the formula, Total = A + B - Both + None
How did you know the last term is 0?
