Answer 6

hold on something is missing from the venn diagram

Answer 7

I didn't make this diagram, this is the question :/

Answer 8

which circle represents the number of people who cleared up?

Answer 9

I think 20% because then there are 20 mabels

Answer 10

I think so, too because it says "given they used the meds"

Answer 11

something is really wrong here
they have two circles, one seems to be the people who used the medicine
the other is the people who did not
but they overlap with 30 people!
how can 30 people use it and not use it at the same time?

Answer 12

but to be sure add up how many things there

Answer 13

I was wondering that same thing!

Answer 14

i think this was written by someone who is confused
not you, the person that wrote the problem
it makes no sense

Answer 15

ok well if i were you i would go with 20% there is 100% there and so that means 20 is 20%

Answer 16

Thanks, guys :)

Answer 17

it looks like you have 20 who used it
10 who did not
30 who both used it and didn't use it, and 40 that apparently are in some other category
maybe they are aliens
