Do you have the rest of the question?
And what have you got so far? (TSR is not a homework service :smile:

I mean can you post the other subjects and numbers of students which are presumably provided in the question?

Draw a bunch of overlapping circles (one for each subject) and fill in what you know

There's 3 circles, 3 in the middle 8 in chemistry 7 in biology and 5 in physics,6 in-between biology and chemistry 4 between chemistry and physics and 2 between biology and physics, the number in the Box Is 6

Ok, so can you work out how many students there are in total?
And how many students study chemistry (by itself or with another subject) – how many students don't study chemistry at all?
