venn diagrams. Please help me

This might be wrong but I think this is how you do it-
Well you already know that 10 people are doing all 3 subjects so they are in the middle.
13 people are doing chemistry and biology but 10 of them are also doing physics so you do 13-10=3 so that's what you put for that bit.
It says that 19 people are doing biology and physics but again as 10 people are also doing chemistry with it, you do 19-10=9 which is what you put in that part.
Again as 18 people are doing chemistry and physics but 10 of them are also doing biology, you do 18-10=8 which you put for that part.
You know that 41 people as a whole are doing chemistry, so you do 10+3+8=21 and then do 41-21=20. This tells you that 20 people are doing only chemistry.
As you know 30 people are doing physics, you do 10+9+8=27 and then 30-27=3 to get 3 people doing only physics.
Then when you add all the numbers together and do 9+3+10+20+8+3=53. As there are 60 students you do 60-53=7 to get the number of people doing just biology and now you have all the figures and you just have to put the numbers in the Venn diagram

This is what I made it too

Yes, you correct! Thank you!

There are 60 students studying sciences (biology, chemistry and physics).
10 students study Biology, chemistry and physics.
13 students study biology and chemistry.
19 students study biology and physics.
18 students study chemistry and physics.
41 students study chemistry.
30 students study physics.

what is the answer
