Yeah but I'm looking at a diagram I don't see how this helps me. Can you explain it please I'm not in the cheating business I just want it explained.

hero · Answer

Have you tried actually solving it first? It's best to at least try to solve it for yourself and describing what you don't understand or ask questions about things you don't know first.

anonymous · Answer

I think the answer is 30% because it is in the middle of the Venn Diagram. Which is where I think people used medicine I know it is not 20% though.

hero · Answer

How do you think the answer is 30%? What reasoning led you to that answer?

anonymous · Answer

Well 20% is wrong because I got it wrong the first time. 40% is wrong because it isn't even in the Venn Diagram. And 10% is wrong because that is skin cleared without using the medicine. Do you think I am right that it is 30%?

Its not 30%!! I just took the test
